Ancient Aliens(2010–)

The Evidence

If ancient aliens visited Earth, what was their legacy, and did they leave behind clues that exist in plain sight such as sophisticated aircraft, complex electrical grids, and intricate construction machinery? Indian Sanskrit texts, dating back to 6000 B.C., describe in varying but vivid detail flying machines called Vimanas. Megalithic stone structures in Egypt reveal evidence of precision saw work. Interpretations of the Jewish Zohar writings offer depictions of a life-sustaining manna machine, eerily similar to chlorella algae processing systems today. Are these examples of modern technology, or is there evidence that these incredible mechanisms existed on Earth thousands of years ago?

The Visitors

If ancient aliens visited Earth, who were they, and where did they come from? Possible historic evidence and beliefs are examined around the world. The Dogon people possess knowledge of a galaxy they claim was given to them by a star god named Amma. The Hopi and Zuni people celebrate Kachinas, gods from the sky, whose headdresses and costumes appear to resemble modern helmets and protective clothing. Halfway around the world, Chinese legends tell of the Han leader, Huangdi, arriving on Earth on a flying, yellow dragon. Was this dragon more likely a spacecraft? Ancient astronaut theorists believe that these are far from chance encounters and that extraterrestrials not only interacted with us, but changed the course of human history.

The Mission

If ancient aliens visited Earth, what was their mission, and is there evidence that points to when they will return? Ancient Sumerian tablets describe an alien race, known as the Anunnaki, who came to Earth to mine for gold. Egyptian hieroglyphs depict hybrid creatures that were part man, part animal. Mysterious crop circles and unexplainable crystal skulls are thought to contain messages that man has yet to decipher. Strange evidence may exist in multiple cultures throughout history suggesting that aliens came here to explore, excavate raw materials, experiment on human beings, and even for pure conquest.

Closer Encounters

Reports of encounters with strange beings and sightings of mysterious objects in the sky have occurred throughout history. A 13th century historical book, Otia Imperialia, includes an account of a creature descending from a flying craft over Bristol, England. The log from Christopher Columbus' first voyage to America contains a report of strange lights in the sky. Medieval art pieces depict disc-shaped objects floating in the heavens. Sightings of flying cigar-shaped crafts were reported during the Black Plague. And there were even discussions of extraterrestrial life among America's Founding Fathers. Could these sightings, coming from every part of the world, from biblical times to present day, be evidence that aliens have been with us all along?

Mysterious Places

Mysterious places can be found around the Earth, and, inexplicably, UFOs are often sited near these mystical areas. Planes and ships unaccountably disappear in the infamous Bermuda Triangle. Strange magnetic anomalies in Mexico's Zone of Silence have not only drawn missiles off their course, but seem to pull meteorites out of the sky. An ancient doorway carved into a sheer rock wall in Peru's Puerta de Hayu Marka is said to be a portal to other worlds. Markawasi's plateau is filled with strange rock formations allegedly left behind by an ancient advanced civilization. What connections do these and other "hot spots" share? Is it possible that ancient extraterrestrials also knew about these mysterious places?

Gods & Aliens

Myths and legends have long been regarded as fantastic stories that describe powerful gods, mutant giants and fearsome monsters. But why do so many different cultures, separated by vast distances, tell the same stories? Is it possible that myths and legends were really eyewitness accounts of ancient astronauts descending to Earth? Ancient texts are filled with stories of gods interacting with humans, offering wisdom, technology, and even impregnating women. Could the demigods of mythology have been the offspring of alien and human unions? If so, could aliens have supplied the Missing Link that accelerated human evolution, advancing our civilization and making us who we are today?

Underwater Worlds

Ancient underwater cities can be found around the globe, but could these aquatic worlds be the ruins of unknown civilizations--or even proof of extraterrestrial visitations? The infamous tale of the long lost city of Atlantis may be a preserved memory of an ancient alien metropolis. Beneath Lake Titicaca in Peru, the ruins of recently discovered temples support local legends of an underwater UFO base. Ancient Indian texts, known as Sangams, describe sunken cities where aliens and humans intermingled thousands of years ago. Who could have built the 600-foot stepped stone structure off the coast of Japan--a site that may predate the Egyptian pyramids by thousands of years? Could evidence of ancient alien contact lie buried in Earth's deepest oceans?

Underground Aliens

If extraterrestrials influenced human history, can evidence of their existence be found in hidden tunnels and caverns around the world? Could a cave in Ecuador contain metallic books inscribed with secrets of alien technology? Was an ancient underground city in Turkey built with alien help... or as a refuge from an alien attack? Rumors of the U.S. military working alongside aliens in a secret base inside a mesa in New Mexico continue to swirl, Native American legends mention strange inner-Earth beings, and recent archaeological discoveries in the Yucatan may point to an extraterrestrial reality behind.

Aliens and the Third Reich

If ancient aliens visited Earth in the remote past, could they have given us advanced technology, past down through human history? And could this technology have helped the Third Reich build mysterious weapons and crafts far beyond the limits of 20th century science? During World War II, there were reports that the Germans built an operational flying saucer, known as the Hanebu, which was said to use mythical technology found in ancient Indian texts. Another craft was rumored to have been constructed with the help of psychics and mediums who claimed to have received detailed blueprints from extraterrestrial beings. Is it possible Hitler's quest for world domination was aided and abetted by ancient extraterrestrial technology that was rediscovered? And could the allegedly rebuilt alien devices developed in Germany have played a role in America's ability to land a man on the moon?

Alien Tech

Super-heated death rays... High-tech rockets... Powerful sonic weapons... Are these examples of modern day science or could these technologies have originated thousands of years ago? Is it possible that early man possessed scientific knowledge far beyond that of our own century? Ancient texts, folklore and art suggest humans witnessed disc-shaped flying machines and fire-spewing chariots. Could these be accounts of flying saucers and rocket ships? And if so, was advanced technology left here by visitors from the stars? Did mankind's quest to unlock the secrets of levitation, anti-gravity and laser technology merely spring from our imaginations or did these ideas come from otherworldly beings?

Angels and Aliens

Biblical texts and ancient lore frequently describe winged creatures carrying messages from the heavens. But are angels merely the product of mankind's imagination--or do they really exist? If so, where do they come from? Ancient astronaut theorists suggest that the Bible's Old Testament reads like a handbook on extraterrestrial visitations. Accounts of angels can also be found in Islamic and Indian texts. Infinite stories around the globe describe unearthly guardians, entrusted to both observe and protect as well as tales of powerful warriors bringing about everything from plague to peace. Are angels really supernatural beings from heaven, or something more? If so, might angels really be travelers--visiting Earth from distant planets?

Unexplained Structures

If ancient aliens visited Earth, can evidence of their existence be found in the mysterious structures that still stand throughout the world? Inexplicably, megalithic structures found on different continents are strikingly similar, and the cutting and moving of the massive stones used to build these magnificent feats would be a struggle for modern day machinery, let alone ancient man. Ancient astronaut theorists suggest that the standing stones in Carnac, France were used as an ancient GPS system for ancient flying machines. The recently discovered Gobekli Tepe in Turkey, which has been dated back 12,000 years, has finely chiseled pillars that experts describe as a Noah's Ark in stone. Is it possible that extraterrestrials assisted primitive man in constructing these unexplained structures? If so, what was the purpose of these grand projects?

Alien Devastations

If ancient aliens visited Earth, were they responsible for catastrophes, wars and other deadly disasters to control the fate of the human race? The story of the Great Flood sent by deities to destroy civilizations exists in many prehistoric cultures. There are ancient descriptions of extraterrestrial battles that caused wide-scale destruction, and even reports of UFOs lurking in the shadows of recent natural disasters. The Book of Revelations and the Dead Sea Scrolls describe a future apocalyptic battle between good and evil that will destroy our world. Are these ancient texts proof that aliens are hostile and planning a violent return? Or might they be our saviors, ensuring our survival as a species during times of devastation?

Aliens and the Old West

Ancient Astronaut theorists believe aliens have been visiting earth for thousands of years. If so, might we find evidence of this even in the stories of America's Old West? In Aurora, Texas, the local cemetery claims to hold the body of an alien whose ship crashed there in 1897. In Utah, petroglyphs depict strange beings wearing what look like space suits. In southern California, 19th century ranchers reported seeing an otherworldly creature emerge from Elizabeth Lake. And even in Tombstone, Arizona, the home of Wyatt Earp and the site of the gunfight at the O.K. Corral, cowboys claimed to have shot at a giant, metallic bird Are these simply campfire tales, or did the cowboys and native people of America's Wild West actually come in contact with alien beings from another - much more distant - frontier?

Aliens and Monsters

Hindu scripture describes an enormous flying creature called a Garuda that shook the ground when it landed on Earth. Is it possible that this monster was actually a misinterpreted alien craft? Are hybrids like the Centaur, the Minotaur and Medusa just mythical creatures of fantasy–or could these ancient depictions of terrifying monsters have been the result of advanced extraterrestrial transplantation procedures?

Aliens and Sacred Places

Are sacred places the product of man's reverence for God--or the result of contact with ancient space travelers? Jerusalem's Temple Mount has been called a heavenly gateway. Islam's shrine at Mecca displays a Black Stone believed to have fallen from heaven. And the temple at Baalbek, Lebanon was built on a massive stone structure resembling a landing pad. Did man encounter divine beings at these holy places, or might they have met ancient extraterrestrials?

Aliens and Temples of Gold

Could gold be the ultimate link between humans and aliens? A church in southern France is said to hold the key to alchemy--and a gateway to another part of the universe. Locals in Cusco, Peru believe UFO sightings are connected to lost gold at the bottom of Lake Puray. And some believe underneath the Great Sphinx of Giza lies an entire library left behind by extraterrestrials--a library stored on gold.

Aliens and Mysterious Rituals

Throughout the world, ancient rites and rituals are believed to connect humans to another dimension. But just who--or what--are we communicating with? Could today's rituals, such as festivals, coronations and funerals, be based on early man's attempts to emulate ancient alien visitors? If so, what other ancient rituals might find their roots in a kingdom--not of this world?

Aliens and Ancient Engineers

Might the tools and technology of ancient builders have come from distant galaxies? Evidence suggests that an ancient mountaintop fortress in Peru was constructed with laser-like tools... temples at Vijayanagara India were built to harness cosmic energy... and an acoustic chamber in Malta enabled interplanetary communication. If the ancient builders did use advanced technology, could it prove that aliens visited Earth thousands of years ago?

Aliens, Plagues and Epidemics

Scientists are continually challenged by unidentified strains of bacteria with mysterious origins. Could some of our most crippling plagues and epidemics be traced to the darkest voids of space--or even extraterrestrial intervention? During the Black Death of the Middle Ages, people reported bronze flying ships emitting a strange mist. As recently as 2011, NASA scientist Richard Hoover published evidence of life in meteorites. Is it possible that ancient aliens--as small as microbes--have shaped human history?

Aliens and Lost Worlds

Mysterious legends and crumbling ruins are all that is left of our planet's lost worlds. But could there be proof of ancient alien visitors hidden among the artifacts of civilizations that have long vanished? Strange carvings suggest the Mayan city of Copan was ruled by the descendants of otherworldly beings. And some believe the ancient Nazca people altered their bodies--and their lands--to signal the star gods to return. Are the astounding accomplishments of lost civilizations merely the products of ancient folklore--or could they have been something... out of this world?

Aliens and Deadly Weapons

Iron swords forged in blazing hot fires... Gunpowder with the power to tear apart human flesh... And rockets capable of destroying entire cities... Throughout history, advances in technology have lead to the development of powerful weapons - each more deadly than the last. But were these lethal weapons the product of human innovation - or were they created with help from another, otherworldly source?

Aliens and Evil Places

For thousands of years, there have been places around the world considered dangerous to humans. Might these locations hold the key to an otherworldly connection? At Australia's Black Mountains, local myths speak of ancient serpent gods and hikers disappearing. Every year hundreds are drawn to a dark forest at the base of Mount Fuji in Japan - to commit suicide. What causes these places to be evil? Could there be evidence that past extraterrestrial activity lead to the negative energy in Earth's evil places?

Aliens and the Founding Fathers

What is the meaning behind secret messages found throughout Washington, D.C.? Did America's Founding Fathers know something about ancient aliens that the general public did not? And if so, could this knowledge have been incorporated into the symbols, architecture, and even the founding documents of the United States of America?

Aliens and Deadly Cults

Mass suicides. Human sacrifices. Unholy rituals. Throughout history, people have claimed to have otherworldly knowledge, and have led followers to commit horrific acts of violence. Are they con men? Are they insane? Or might the voices in their heads really be of an extraterrestrial origin? And if so, did they simply misinterpret the messages they received? Or might there be extraterrestrials with a sinister agenda?

Aliens and the Secret Code

Megalithic monuments linked together by electromagnetic energy... Prehistoric ruins arranged across vast distances in straight lines... And advanced mathematics carved into landmarks more than 5000 years ago. Were ancient man's spectacular structures built by humans alone? Or do they bear evidence of being designed - and interconnected--by otherworldly visitors?

Aliens and the Undead

Zombies rising from their graves... Blood sucking vampires damned for all eternity... and humans trapped in a life and death struggle between heaven and hell. For thousands of years, mankind has told tales of encounters with strange, soulless creatures. Are these beliefs merely manmade fabrications - or could there be extraterrestrial origins in earthly encounters with the undead?

Aliens, Gods and Heroes

Superhuman strength... Supernatural powers... And the awesome ability to fly. Throughout history, mankind has told incredible tales of gods with extraordinary powers. But are these accounts merely tall tales, or could they be based on factual events? If mythical gods really did exist, were they, as ancient astronaut theorists believe, extraterrestrial beings? And could this help to explain the enduring popularity of gods, titans and other so-called "super-heroes"?

The Mayan Conspiracy

The Mayan civilization dominated Central America for nearly 2000 years, but by the 9th century A.D., the great Mayan cities were abandoned, and the Mayan people vanished. What could have happened to this advanced culture? Might the Maya have left clues as to how they surpassed other cultures in science, mathematics, time keeping, and most importantly, astronomy? In recent years, hieroglyphs have been decoded to reveal that the Maya were able to accurately predict shifts in the Earth's axis every 26,000 years. Inscriptions on the sarcophagus of their most prominent ruler, King Pakal, tell of a journey to the Milky Way. And a sophisticated calendar foretells of the end of the world in 2012. Most striking is their belief that knowledge was passed to them by otherworldly beings who descended from the sky. Could the ancient Maya have actually conspired with extraterrestrial visitors to plan the future--and even the very end of the world?

Aliens and Stargates

Legends from around the world speak of sacred entryways to the land of the gods. Gates that allowed instant passage not just beyond the confines of Earth, but beyond space and time. Are such passages--or stargates--just inventions of myth, or might this kind of interstellar travel have existed in the ancient world? In Turkey, researchers uncover a mysterious and toxic cave that the ancient Greeks described as a physical gateway to Hell. The Incas believed their empire began when divine beings stepped through portals in a mountain. In Northern Mexico, legends describe strange, otherworldly creatures appearing and disappearing within the remote ruins of an ancient civilization. As science continues its quest to create technology that would allow humans to travel to the stars, is it possible that these celestial pathways already exist?

Forbidden Caves

Could the darkest recesses of our planet contain important information left by our ancient ancestors? And within Earth's mysterious caves, might we find evidence of otherworldly contact? Throughout human history, some caves have been considered sacred places for spiritual encounter and enlightenment, while others have been feared as true portals to purgatory. What happens in these subterranean spaces that has the power to influence religions around the globe? Could some of Earth's deepest caverns be secret conduits to supernatural realms? In Charma, India, archeologists recently discovered 10,000 year-old prehistoric artwork of what appears to be extraterrestrial beings. Could these paintings be a visual record of alien encounters in the distant past?

The UFO Conspiracy

In 2017, news breaks that the Department of Defense recently spent millions investigating reports of UFOs; the latest disclosure about a series of secret government UFO projects dating back decades.

Da Vinci's Forbidden Codes

Researchers claim there are hidden messages that can be found within the works of Leonardo da Vinci--and other art throughout history--that may reveal an extraterrestrial influence.

Return to Antarctica

Antarctica may serve as home base for extraterrestrial visitors to Earth, but as human exploration of the frozen continent increases, humans may come face to face with the ruins of an ancient advanced civilization buried beneath the ice.

The Badlands Guardian

Satellite images have revealed a giant face that appears to be carved into the Earth in Alberta, Canada, which has now become known far and wide as "The Badlands Guardian."

The Lost City of Peru

Giorgio A. Tsoukalos, David Childress and William Henry examine a recently discovered lost city in Peru that has upended the historical timeline of South America, revealing that civilization emerged thousands of years earlier than previously thought.

Top Ten Mysterious Sites

Ancient Aliens is counting down the world's top ten most mysterious sites, from the towering Moai statues of Easter Island to the enormous megalithic blocks of Stonehenge to the precision cut stones of Puma Punku. Could these extraordinary places provide evidence of extraterrestrial visitation?

The Mystery of Nan Madol

Giorgio Tsoukalos and David Childress explore the mysterious chain of manmade islets in Micronesia's Nan Madol; built from 250 million tons of volcanic rock, there are local legends that strange visitors floated the massive rocks through the air.

The Relics of Roswell

In 1947, the U.S. military collects debris from what they claim is a crashed weather balloon outside of Roswell, N.M.; new evidence may prove that the wreckage belonged to an alien spacecraft and that remnants may have been overlooked.

Secrets of the Pyramids

For thousands of years, pyramids were the largest structures on Earth. The best known were constructed in Egypt and Central America, but others have been found all around the world, including in China, Africa and Indonesia. But what purpose did the pyramids serve? Researchers explore strange similarities between all pyramids, as well as the geographic, strategic and otherworldly connections between these mysterious monumental structures.

Aliens and Cover-Ups

In 1980, three young military men were sent into a UK forest to investigate strange lights. They reportedly encountered a spacecraft of unknown origin. When one of the men touched it, he claims to have received telepathically a long sequence of binary code, which he later wrote down and translated. The military ordered them to never speak about the incident. Why do such UFO encounters continue to be kept under wraps, and what might they reveal about our ancient past?

Alien Power Plants

Egyptian hieroglyphs depict the use of light bulbs in tombs and secret chambers. And batteries may have been discovered among artifacts from Mesopotamia. Did the Ancients understand electricity, and if so, how did they discover this technology? Might they have had help from extraterrestrials?

Destination Orion

Why were ancient civilizations around the world so focused on the Orion constellation? While scientists site many earthly connections, researchers suggest this point in the night sky may have been a so-called Stargate, or entry point, for alien life forms. If extraterrestrials have been visiting Earth for thousands of years, might they have originated from the Orion Nebula?

The Einstein Factor

Was Albert Einstein a genius? Or was he superhuman? Was his genius ‘of this world,’ or was it ‘otherworldly?’ Is it possible, as Ancient Astronaut theorists believe, of an extraterrestrial connection to the scientific genius of famous historical figures such as Albert Einstein, Galileo, Archimedes, and Aristotle?

Secrets of the Tombs

Across the globe, archaeologists have uncovered ancient tombs filled with strange items and writings. Remarkable similarities have been found at each of the sites. How is it possible that the burial chambers of distant cultures were so similar in design? Ancient Astronaut theorists believe that some of these complicated and technically advanced tombs were designed with the help of extraterrestrials.

Prophets and Prophecies

They were the messengers of divine knowledge and seers who shared visions of the future. For thousands of years, human civilization has been guided by the words and deeds of ancient prophets, but just who--or what--were these prophets communicating with? Might the experiences of history's prophets be evidence of communication with a heavenly source--or were seers like Elijah and Joseph Smith actually communicating with extraterrestrial overlords? And if so, are there similar prophets at work today?

Beyond Nazca

Erich von Daniken's landmark book, Chariots of the Gods, brought attention to the mysterious phenomena of the Nazca Lines. Hundreds of gigantic lines, some in the shape of animals, geometric patterns and even an alien-like being, extend for miles throughout a remote Peruvian desert. Scholars are divided as to who built them, and why. Some Ancient Astronaut theorists believe that the massive markings have an extraterrestrial connection, and perhaps the ancient people of the region created these gigantic figures in tribute to the gods who visited them. And with one of the largest deposits of nitrates in the world--a key ingredient in rocket fuel and weaponry--could Nazca have been a mining operation for advanced beings in the distant past?

Strange Abductions

In 1975, Travis Walton claims to have been abducted and taken aboard a space ship inhabited by extraterrestrial beings. Several people witnessed his encounter and nearly 40 years later Walton's story of alien abduction, missing time and mind-telepathy manipulation has not wavered. But researchers say that abductions are not a modern phenomenon. The Hebrew Bible is filled with stories of abductions by otherworldly beings. Jonah, Moses, Ezekiel and Enoch all depict what can best be described as physically being taken to other dimensions and then returned. Is it possible that extraterrestrial beings have been abducting humans for thousands of years and if so, might there be an alien agenda behind the phenomena?

The Von Daniken Legacy

A young man's spiritual journey. A controversial bestseller. And a scientific theory that threatened to change the world. Just what are the facts behind Erich von Däniken and Ancient Astronaut theory? For more than 40 years, his books have sold over 65 million copies worldwide. He is a hero to some, and a heretic to others--but Erich von Däniken's controversial theories have captured the attention of the world and ignited a movement known as Ancient Astronaut Theory. His exhaustive search for the truth about mankind's otherworldly origins have started to gain acceptance with a small but growing number of Ancient Astronaut theorists--men and women who have expanded, and at times refined, von Däniken's findings. Did ancient astronauts really come to planet Earth? And, if so, what was their purpose? And perhaps even more important--will they come again?

The Viking Gods

They were teachers and destroyers. Mighty warriors who blazed across the skies in gleaming chariots and wielded magical weapons that could bring down mountains. Odin, Frey and Thor. The gods worshipped by the Norse Vikings were fearsome and mysterious, but were these beings truly divine, or is there, perhaps, an extraterrestrial connection? The Norse were among the most technologically advanced cultures of the ancient world. They were epic explorers who embarked on oceanic voyages to Africa and the Middle East and even reached North America at least 500 years before Christopher Columbus. Were the Norse guided by powerful gods, or could the super-beings that guided the Vikings have actually been visitors from another planet?

The Alien Hunters

In the 21st century, mainstream scholars, scientists, and world governments have for the first time openly joined the hunt for intelligent life beyond Earth. But while such an effort has never been made public before, in reality, the search for proof of extraterrestrial life has been underway for decades. Starting around 1947, a series of unexplained sightings and mysterious events forced certain high-level members within the US government to officially become alien hunters. Projects Sign, Grudge, and Bluebook were government programs to research UFO sightings--and by some accounts, literally hundreds of the reported events were unable to be explained. Ancient Astronaut theorists suggest there is evidence that similar endeavors were even made thousands of years ago, sighting ancient astronomical observatories found all over the world, and new evidence that Babylonians were tracking the movements of the planets over 2,000 years ago.

Forged by the Gods

Artificial metallic objects dating back hundreds of thousands of years. New discoveries of metals once thought to be mythological. Mysterious metal spheres defying the laws of physics. Could these out of place artifacts be physical evidence of extraterrestrials visiting planet Earth in the distant past, leaving behind remnants of their technology? Ancient Astronaut Theorists Erich von Daniken and Giorgio A. Tsoukalos travel to Romania to take a closer look at an ancient aluminum wedge that has left historians baffled. And investigative journalist, Linda Moulton Howe, travels to Jacksonville, Florida to uncover the secrets of a strange metallic sphere that fell from the sky and garnered the attention of the U.S. Navy. Might evidence of our extraterrestrial past be found in these mysterious and ancient metal objects?

The Mystery of Rudloe Manor

In the southwest corner of the Wiltshire, England countryside lies the mysterious structure known as Rudloe Manor. On the surface, it appears to be nothing more than a quaint English manor house, but researchers have argued for years that it has been the epicenter of British research into UFOs since World War II. British Ministry of Defence (MOD) insiders claim that an astounding 2.2 million square feet of vast caverns divided into many smaller chambers lie buried underneath Rudloe Manor. Giorgio A. Tsoukalos and Nick Pope explore the possibility that important files related to the history of the UFO phenomenon are being kept under lock and key here. Might recovered extraterrestrial craft be stored and analyzed there as well? Could the evidence of extraterrestrial contact from the Berwyn Mountains incident in 1974 and the Rendlesham forest encounter in 1980 be hidden in this highly protected facility?

The Alien Architects

Many of the architectural marvels of the ancient world bear striking similarities to one another, even though they were built by civilizations that were separated by thousands of miles and are believed to have had no contact with one another. Separated by more than 7500 miles, the Giza pyramid complex in Giza, Egypt and the Avenue of the Dead in Teotihuacan, Mexico contain pyramids that are aligned with the constellation of Orion's belt. An ancient pyramid temple in Cambodia known as Baksei Chamkrong is an almost identical match for the Temple of the Jaguar in Guatemala. Many structures built using stone slabs that weighed over a hundred tons. But how did primitive people achieve such extraordinary feats? And why do we see such similarities? Could these sites have all been designed by alien architects?

The Pharaohs' Curse

According to legend, an ancient curse was placed upon the tomb of King Tutankhamun, and when that tomb was opened in 1922, a series of terrible events occurred. A curse was also placed on King Tut's father Akhenaten, and during the rehearsal of a play dramatizing the lifting of this curse, similar tragedies followed. Could a curse truly exist, but in the form of alien technology that is protecting an incredible secret about our past? Is there hidden power in the words inscribed on so-called "magic bricks" found in King Tut's tomb, or in those contained in the play to lift Akhenaten's curse that are connected to some extraterrestrial force? Ancient Astronaut theorists suggest that The Pharaohs' Curse was put in place to protect not only the truth about an otherworldly event in our past, but also an extraterrestrial device--a device that some believe still exists today, buried deep beneath the Earth... on Oak Island.

The Science Wars

Nearly every year archaeologists and anthropologists make discoveries that require revisions to our history books. But there are numerous artifacts that are outright ignored because they don't fit into the accepted scientific paradigm. Could clues about our extraterrestrial origins be hidden in these discarded pieces of our past? Shocking evidence has recently been revealed that challenges the accepted dating of the Great Pyramid. An ancient hammer found in Texas that dates back 140 million years is ignored by mainstream archaeologists. And unexplainable elongated skulls have been found on nearly every continent of the world that science refuses to test. Could we be on the brink of scientific discoveries that the academic community cannot deny? Evidence that reveals the truth of where we really came from, why we are here and if we are alone in the Universe?

City of the Gods

The ancient site of Teotihuacan in central Mexico--which the Aztecs called the "City of the Gods"--is one of the world's greatest mysteries. To this day, no one knows who built the metropolis or what happened to its occupants, but based on evidence that has recently been unearthed, Ancient Astronaut theorists suggest it was once home to a highly advanced, perhaps extraterrestrial, civilization. The many structures that still stand in Teotihuacan appear to be encoded with advanced mathematical and cosmic principles, and the layout precisely mirrors the positions of the planets in our solar system. Modern excavations at the site have unearthed discoveries of liquid mercury, walls lined with mica, and strange golden-spheres containing unknown substances--all of which are out of place in the ancient world. Could these artifacts be the remnants of an alien society? Perhaps even an extraterrestrial spaceport?

The Alien Frequency

The use of mantras and chanting to connect with a higher plane has existed in cultures all over the world dating back thousands of years, but why would people who had no contact with each other all subscribe to this practice? Could there be certain frequencies that connect us with greater--perhaps extraterrestrial--forces? Researchers have found that dozens of megalithic sites stretching across the globe--like the prehistoric Newgrange monument in Ireland, the chiseled labyrinths underneath the island of Malta, and the giant temple complex of Angkor Wat in Cambodia--were all designed to emanate the exact same frequency. The planets in our solar system each give off a distinct sound, and certain places on Earth, like Taos, New Mexico, have been found to produce a hum from an unknown source. Might the best evidence of alien intervention on Earth be found not with our eyes... but with our ears?

The Majestic Twelve

In 1984, a roll of 35mm film surfaced from an anonymous source that contained pictures of what is now known as the Eisenhower Briefing Document. This document is purported to be a memo sent from the director of the CIA in 1952 to president-elect Dwight Eisenhower, informing him of the existence of a top-secret group within the US government called "The Majestic Twelve." Composed of top scientists, government officials, and military elite, this group's mission was to investigate reports of unidentified flying objects--and to examine crashed extraterrestrial craft. And more recently, in 2002, a major computer hack into Pentagon and NASA computers appears to reveal hard evidence that not only are the Majestic Twelve documents real, but that the government's interaction with extraterrestrials has led to the creation of a secret space program, that has already established bases on the moon, Mars, and other celestial bodies.

The Akashic Record

Throughout history, prophets and visionaries have claimed to be able to telepathically access knowledge and information that would ultimately steer the course of human history. But if true, where do these individuals get their visions? According to ancient mythologies, there is a universal repository of knowledge known as the Akashic Record. While most mainstream scholars relegate this to the realm of mythology, recent scientific discoveries have opened the possibility that such a repository could actually exist--and is accessible by the human mind. Giorgio A. Tsoukalos meets with neuroscientist Dr. Dario Nardi to measure the brainwaves of Dr. Deepak Chopra as he enters a state of deep meditation to observe the physical chnges in the brain as he connects or taps into something beyond ourselves. Could our ability to tap into the Akashic Record lead to the next giant leap in human evolution--and connect us to other intelligent beings throughout the cosmos?

Voices of the Gods

India's Sanskrit texts are filled with incredible stories about advanced technology in the ancient world. Highly complex building techniques, brain surgery, flying crafts, and even nuclear physics are described with uncanny accuracy. Hindu scholars attribute this knowledge to a time when "gods" walked among men. Might this period of time actually be referring to an age when extraterrestrials inhabited the planet? Giorgio A. Tsoukalos travels to India to further explore the Sanskrit texts, as well as the structures and technology that have stood the test of time. From a temple that inexplicably survived a major earthquake to evidence of ancient brain surgery and instructions for advanced flying machines, Giorgio studies the sacred knowledge that is said to have come directly from the voices of the gods.

The Animal Agenda

Extraterrestrials are almost always envisioned as humanoid, but is this an egocentric concept? Could it be that intelligent alien life looks much different from us, and that some extraterrestrials more closely resemble other animals? And is it possible that many of the animals that roam the Earth have otherworldly origins? By examining ancient cultures around the world, we find that nearly all revered certain animals and depicted their gods with animal traits. The Sanskrit epics of India feature gods in the form of elephants, monkeys, and snakes. The Sumerians depicted gods with bird heads and wings. And in Egypt, not only did they portray many of the gods with animal features, but they even went so far as to mummify their animals. Ancient Astronaut theorists suggest that certain animals may not have developed through Darwinian evolution, but were planted here by alien visitors.

The Replicants

Across the globe, over 1.5 billion people believe in reincarnation, the belief that a soul can be reborn into a different body after death. Major universities worldwide have departments devoted to the study of reincarnation and according to their research there is a mounting body of evidence that suggests some people have the ability to vividly recall past lives. Ancient Astronaut Theorists suggest that not only does reincarnation exist, but our extraterrestrial ancestors specifically designed the human body to be a vessel for otherworldly entities. World leaders, like the Dalai Lama and even Saddam Hussein, claim to be the reincarnations of powerful figures from the past–figures with an extraterrestrial connection. If souls are indeed recycling through various embodiments, is this simply the natural continuation of life–or might this process be directed towards some greater end? One that reaches far beyond Earth?

A Spaceship Made of Stone

In Honshu, Japan, stands one of the country's oldest and holiest Shinto shrines--the Ishi-no-Hoden megalith. Carved from a single rock and weighing roughly 500 tons, it appears to hover over a pool of water, and according to Japanese legend, it was built to depict a sky ship made of stone that the ancient people witnessed descending from the heavens. Ishi-no-Hoden is just one of numerous megalithic structures found throughout Japan commemorating a time when the gods--or, perhaps, extraterrestrial beings--descended to Earth. Centuries old texts describe in vivid diagrams strange craft that have appeared in the sky and on the shores. And satellite images of Mars have revealed keyhole-shaped structures identical to some of Japan's oldest tombs. Could Japan's origins lie beyond Earth, and might a surge of recent UFO sightings provide clues that the island nation provides the key to reconnecting mankind with its extraterrestrial past?

The Alien Disks

Hundreds of strange disks are discovered in a cave in China that appear to tell the story of an ancient extraterrestrial crash on Earth. Shortly after the disclosure of these artifacts, the disks are confiscated by the Chinese government and dismissed as a hoax. But are they? Ancient traditions from around the world speak of mysterious disk-shaped artifacts that held tremendous power. The Babylonians claimed to have a disk that stood in for their most powerful deity. The Incan leader Pachacuti attributed his rise to a divine disk that fell from the sky. And treasure hunters have been searching for centuries for the acclaimed “Golden Sun Disk” that was hidden from the Conquistadors when they sacked Peru. Ancient Astronaut theorists propose that these disks were more than just sacred objects, and represent some sort of extraterrestrial technology.

Alien Transports

Ancient cultures around the world tell stories of strange objects witnessed flying in the sky. But are these tales fiction, or might people living thousands of years ago actually have seen extraterrestrial crafts descending from the heavens? In the Hebrew Bible's Book of Ezekiel, the prophet describes a fiery chariot containing wheels within wheels, powered by angels. In ancient Ethiopian texts, King Solomon of Israel gave the Queen of Sheba a flying carpet, and traveled on one himself throughout the Middle East. And Chinese mythology explains that the god Huang Di emerged from the belly of a fire-breathing dragon to become China's first emperor. Could these accounts of fiery chariots, flying carpets and fire-breathing dragons really be descriptions of misunderstood technology involving mysterious crafts? Have otherworldly spacecraft been soaring across Earth's skies for thousands of years? What were our ancestors really describing in their ancient stories?

Mysterious Structures

All over the world there are megalithic stone structures whose construction baffle stonecutters, scientists and archeologists. Is it possible that ancient humans managed to move and cut these gigantic rocks with the help of alien technology? From the 3,000 megalithic stones in the French village of Carnac to the precision-cut blocks at Puma Punku in Peru to the 12,000 year-old circular structures of Gobekli Tepe, carved multi-ton megaliths are found throughout ancient cultures. Yet the mystery of how the stones were cut and moved to build these formations remains. One possible answer may be found at Coral Castle, Florida, where in the 1930s an anti-gravity device was allegedly used to move 30-ton coral blocks to create the giant sculpted gardens. Massive stone ruins mark what we believe to be ancient burial sites, temples and astronomical observatories--but how these megaliths were built cannot be explained.

Mysterious Devices

A 2,000-year-old computer... a power plant inside the Great Pyramid... and a Nazi-era time machine with roots in the ancient history. Throughout the world, there are artifacts and stories that point to advanced technology in the distant past. Could these devices be products of our ancestors' imaginations or might ancient man have had access to extraterrestrial technology? Were ancient Egyptians able to generate electricity, perhaps even illuminating the corridors of the royal tombs with electric light bulbs? Did top-ranking Nazis secretly develop a time-travel machine that was used as an escape vehicle after their defeat in Europe? Could the Ark of the Covenant have been a sonic weapon? Many of the world's most mysterious devices have been here for thousands of years. Could they have been built with the help of extraterrestrial beings?

The Reptilians

The Reptilian alien is a fixture of science-fiction, from H.P. Lovecraft's tales of Valusians to the Cardassians in Star Trek, to the Visitors of the television series V. But could ancient myths about reptilian creatures provide evidence that they are more than just a pop-culture creation? Legends of serpent beings can be found on every continent. The Bible, the Quran and the ancient texts known as the Nag Hammadi codices all describe reptilian entities interacting with humans. In Mexico and Central America people worshiped the feather serpent god called Kukulkan or Quetzalcoatl. In India, the Nagas are half-human half-reptile gods who live underground in a place called Patala. And in China and Japan, many emperors claim to be the descendants of dragons. Could these stories represent real Reptilian beings that people all over the world actually encountered in the ancient past?

The Tesla Experiment

He is one of the most prolific inventors of the 20th century--and the man that actually electrified the world. Nikola Tesla shepherded mankind to a new industrial era and laid the groundwork for today's technological age--but could that have been by some otherworldly design? A man shrouded in mystery and intrigue, Tesla would speak about obtaining insights in a flash of genius, how he could visualize his inventions in full-detail and manipulate them in his mind, and his compulsion to invent the future. But he also claimed to have direct communication from intelligent beings on other planets. Is it possible that this alleged mad scientist, so far ahead of his time, was actually a human "receiver"? A being tapped to advance mankind--and pave the way for a future reunion with our alien ancestors?

The God Particle

It has been called the key to the universe and possibly the most important scientific breakthrough of all time. Could the so-called "God Particle" reveal the truth about our origins? And might clues to its significance have been left here on Earth thousands of years ago by extraterrestrial beings? The age-old question, "where did we come from?" remains a mystery, but in 2012, scientists at CERN laboratory announced the discovery of the "God Particle"--the subatomic particle that is believed to give mass to matter--and offers a closer understanding of just how the universe began. The discovery seemingly pitted science against religion. But could science and religion actually be kindred spirits? Many ancient religions and mythologies describe the origins of the universe in ways very similar to today's scientific explanations and proclaim that this information was given to them by otherworldy beings.

Alien Encounters

Stories of strange encounters accompany many of history's major events. Is it merely coincidence? Or might it be evidence of extraterrestrial intervention? In ancient myths from cultures around the globe, gods are often portrayed intervening in human affairs. The Sumerian gods are said to have created mankind; the Hebrews believe God gave Moses man's first laws, the Ten Commandments, and the angel Gabriel reportedly shared divine wisdom with the prophet Muhammad. But is it possible that these supernatural visitations were not actually the work of the gods--but rather a race of extraterrestrials using advanced technology to create and shape our civilization? Ancient Astronaut Theorists believe aliens may have helped guide mankind in the remote past--and that evidence for this stunning conclusion can be found sprinkled throughout human history.

The Power of Three

Reverence for the number three dates back thousands of years, and can still be found today in art, architecture, science, literature, and religion. What is it about this number that continues to fascinate mankind? Could this recurring motif contain a profound message? The ancient Egyptians believed the design of the three pyramids of Giza came from the Gods. Diverse cultures across the world worshipped divine beings that ruled as all-knowing triads. Isaac Newton searched for the secrets of the universe in an ancient tablet that spoke of the power of the number three. Even the language of our DNA is written in a pattern of threes. Could the combination of all the trios and trinities embedded throughout the mythical and religious world suggest that the power of three might somehow connect humanity with divine or, as some would believe, extraterrestrial forces?

The Crystal Skulls

Luminous relics in the shape of human skulls. Otherworldly artifacts believed to harness the secrets of the universe. Are the Crystal Skulls part of an elaborate hoax? Or do they possess a great, perhaps even otherworldly power? The Crystal Skulls are some of the most controversial of ancient artifacts. While there have been literally hundreds of crystal skulls found throughout the world, according to legend, there are only thirteen which are believed to hold an awesome, mystical power whose secrets will be revealed when the skulls come together to form a global grid. Could this so-called "reunion of the skulls" awaken sacred knowledge of the gods? Knowledge that has been hidden from mankind for thousands of years? And if so, will the Crystal Skulls reveal the truth about our extraterrestrial past, or offer us a glimpse into our future?

The Anunnaki Connection

The Sumerians in ancient Mesopotamia achieved over one hundred "firsts" for human civilization. Advances in writing, agriculture, science, mathematics, medicine, astronomy, transportation, building, military, schools and city planning, all originated in Sumer. The Sumerians credit these achievements to The Anunnaki--giant, winged gods, who are only found in ancient cuneiform texts. Could these gods be more than legend? Is it possible that civilization made sudden, huge advances in development 5,000 years ago as a result of the Anunnaki's presence on Earth? Could the human race have been jump-started or even genetically created by extraterrestrial beings in the remote past? Might the Sumerian texts describing the Anunnaki be proof of this controversial theory? And if so, could we someday reunite with these celestial visitors?

Magic of the Gods

Wondrous wizards... Mysterious sorcerers... And heavenly beings... possessed of unimaginable power. Throughout the ancient world, magic was used for everything from healing to communicating with the gods. But did magic really exist in the ancient times? Not as a form of theater--but as a means of replicating the power of the gods? Do ancient accounts of magic suggest evidence of advanced, otherworldly knowledge? A knowledge given to early humans as a means of helping them unlock their own - some might say "divine" - potential?

The Satan Conspiracy

He is the evil one, the Prince of Darkness, the ruler of Hell. Satan conjures up horrifying images of a horned beast whose sole purpose is to destroy humanity. Yet there is evidence that the fallen angel we know as Satan may be misunderstood. New interpretations of ancient texts indicate that Satan may have been an extraterrestrial who was more of an ally to humanity than an enemy by passing along knowledge that planted the seed for civilization. Could Satan's reputation as the personification of evil be his punishment for leading early man out of darkness and ignorance? If so, might his evil acts really be expressions of revenge against the human creatures that abandoned him? Or are the devilish deeds associated with Satan part of a grand plan? A series of moral challenges intended to prepare us for our next, and perhaps final... close encounter?

Alien Operations

Mysterious surgeries performed by early humans... Strange beings with miraculous powers... And a cover up--destroying centuries of scientific knowledge. Are recent breakthroughs in medicine the result of years of research? Or does the knowledge of healing really come from an otherworldly source? Evidence of advanced medical procedures practiced in the ancient world has been found everywhere from carvings on the walls of temples to actual skeletal remains. But just who were the practitioners of this extraordinary science? And where did their knowledge of the human body come from? Accounts from various cultures describe similar divine, birdlike figures that brought advanced medical knowledge to mankind thousands of years ago. Who--or what--were these ancient surgeons? Is it possible that these Gods may have been extraterrestrial beings that came to Earth to teach humans how to heal themselves?

Emperors, Kings and Pharaohs

Powerful monarchs ruling by divine right. Centuries-old dynasties amassing enormous wealth. And legendary leaders wielding powerful weapons of mass destruction. Is it possible that ancient rulers were, in fact, connected with divine or, some would say, extraterrestrial forces? And, if so, what was their purpose? Ancient emperors, kings, and pharaohs were often attributed with otherworldly strength, ability, and wisdom; many were even considered gods by the people they ruled. Who were these exceptional leaders, and how did some accomplish so much in their time? Ancient Astronaut theorists believe that these great rulers throughout history were "chosen" and guided by extraterrestrials. Is it possible that the world's legendary leaders might have shared a common genetic trait? A so-called, "leadership gene"? And might this gene have been–not a product of genetic evolution–but inherited by mankind from some otherworldly source?

Mysterious Relics

Sacred bones… Golden hats… And fragments of sacred objects thought to possess healing properties. All around the world, archaeologists have uncovered mysterious relics revered by ancient cultures for thousands of years. Now on display in museums, temples and churches, millions of people travel great distances just to be in their presence. What is it about these ancient objects that draws people to them? Could the truth of mankind's origins be found in the fabric, metal, stone and bones of our distant past? And could these mysterious relics really provide us with the ability to access divine or otherworldly power?

Aliens and Forbidden Islands

Legends of lost and mysterious islands, advanced civilizations and Eden-like paradises have been told by sailors throughout human history. Is it possible these stories are more than just the myths of imaginative seafarers? Might evidence of our Ancient Alien origins be found by exploring the world's most remote islands--strategic spots where extraterrestrials may have once made their earthly homes... and possibly still visit today? Unidentified submersible objects going at lightning speed... strange crafts coming out of water near remote volcanic islands... and mystifying megalithic ruins in the middle of the ocean. Is it possible UFO activity could be hidden deep underwater and off the coasts of islands? Could this explain why so many islands around the world have stories of unexplained sightings of objects both overhead and beneath the sea going back centuries?

Aliens and The Lost Ark

The Ark of the Covenant is one of the most sought after religious relics of all times and far more than just a box that contained the Ten Commandments. The biblical stories surrounding the Ark speak of a device with divine powers that was able to produce food, take down stonewalls, kill those that come in contact with it, and provide direct communication to God. Are these stories mere myth? Or did the Ark of the Covenant possess extraordinary powers? What happened to this incredible relic? Could it still be hidden? Are we getting close to a rediscovery--and reactivation--of the Ark? And if so, will the Ark of the Covenant reveal a long, lost connection to our extraterrestrial past?

Pyramids of Antarctica

Is there evidence of ancient technology buried beneath the ice of the most southern continent?

Destination Mars

Within 20 years, we are expecting to send the first colonizers to the Red Planet. Astronauts will brave the six-month journey to become the first extraterrestrials visitors to Mars--where they are expected to live and die there, never to return to Earth. But why have we always had a strange fascination with this particular planet? The latest NASA research has revealed that not only is there evidence of liquid water on the planet, but that life on Earth was most likely seeded on Mars. Ancient Astronaut theorists even suggest that the development of life on Earth may have similarities to how scientists are currently planning to keep humans alive on the red planet. Could extraterrestrials from Mars have colonized Earth in our remote past? Could our voyage to Mars not only unlock the mysteries of our ancient, extraterrestrial origins--but also be the key to the long-term survival of the human species?

The Next Humans

In the 21st century, technology is heading in a radical new direction--the merging of man and machine. Smart drugs, nanorobots, and machine-printed organs are just a few of the cutting-edge innovations catalyzing the evolution of humankind into an entirely new species. Transhumanists envision a future in which we become cyborgs, achieving far superior intelligence, the ability to survive beyond Earth's atmosphere without a spacesuit, and the possibility of immortality. But might similarly superhuman beings have walked the Earth once before? Beings that our ancestors regarded as gods? Ancient Astronaut theorists say yes, and suggest that we are simply following the course they set us on from the very beginning of mankind--to transcend our flesh and become like our extraterrestrial creators.

The New Evidence

Millions of people around the world believe we have been visited in the past by extraterrestrial beings. What if it were true? This is the question Ancient Astronaut theorists have posed since Erich von Daniken's Chariots of the Gods was first published in 1968; examining scientific, archaeological, astronomical, and historical evidence to find the answer. In recent years, more new evidence has been revealed than ever before that suggests there was extraterrestrial intervention on Earth in the distant past. Satellite images have exposed geoglyphs resembling Nazca lines in Kazakhstan. Ground penetrating radar has detected remnants of ancient technology in Machu Picchu. And thermal scanning has uncovered hidden chambers behind King Tut's tomb that may hold the remains of extraterrestrial beings. Could we be at the tipping point where the overwhelming evidence outweighs any last shred of doubt?

The Visionaries

Scientists theorize that when mankind encounters extraterrestrials, we'll need to speak to them through the universal language of mathematics and binary code. But is it possible that extraterrestrials have already been communicating with our greatest mathematicians and engineers? Might they have somehow aided them in bringing about the space age and computers? Ancient Astronaut theorists say yes. As evidence, they point to the true father of the space program, Nikolai Fyodorov, a "Cosmist" who believed that human civilization had its origins in outer space and that it was our destiny to return to the cosmos. Wernher von Braun was greatly influenced by Fyodorov and he was motivated by a similar, secret belief when he ran the mission that put the first man on the moon. Is it possible that humanity's greatest visionaries have been carrying out an extraterrestrial master plan?

Decoding the Cosmic Egg

A "Cosmic Egg" -- in which the universe, or some primordial being comes into existence by the hatching of an egg -- is found in the creation myths of many cultures. Why is this concept so pervasive throughout the world? Clues to the origin of the Cosmic Egg may lie in another symbol commonly paired with the egg -- the symbol of intertwined snakes -- which some believe represents ancient knowledge of the DNA double-helix spiral. Did our ancestors have advanced insight into human biological coding? And could the Cosmic Egg represent, not the cosmos or the gods, but our own creation and genetic manipulation? Ancient Astronaut theorists suggest that just like the world's most iconic religious symbols, the Cosmic Egg cannot be summed up as representing a singular thing, but may have a much deeper meaning.

The Wisdom Keepers

The Aborigines of Australia are the oldest, continuously surviving society on Earth. The stories preserved in their oral tradition are said to date back over 60,000 years, to an era they call the "Dreamtime" and contain fascinating descriptions about how life began and our planet was seeded by extraterrestrials. Linguistic experts have just discovered that many of these indigenous legends can be scientifically verified by examining the geological record. Ancient Astronaut theorists propose that if the Aboriginal's oral traditions are indeed this accurate, then perhaps the tales they tell about sky gods visiting Earth in large, fire-spewing crafts are true as well. Could the ultimate evidence about our extraterrestrial past be found within the sacred stories, sites, and rituals of Australia's Wisdom Keepers?

The Mysterious Nine

In 2013, former Canadian Minister of Defense, Paul Hellyer, made a shocking claim--that there is a federation of extraterrestrial beings monitoring and guiding humanity. But why would such an esteemed politician make such a controversial announcement? Ancient Astronaut theorists believe evidence can be found throughout history to prove his claims are true. Stories of emperors, kings and pharaohs consulting a pantheon of nine gods can be found in virtually every culture across the globe. Even channeling sessions conducted by CIA scientists in the 1950s connected with an otherworldly group of entities called "The Nine" -- extraterrestrials here to influence the events on Earth. Could there be an intergalactic council of nine secretly working behind the scenes, dictating the course of humanity?

The Hidden Empire

Ancient Astronaut theorists suggest that evidence of extraterrestrial visitation exists in every corner of the Earth, but some say the most compelling can be found in one of the world's least accessible places--China. China is the cradle to one of mankind's earliest and most influential civilizations. The advents of gunpowder, paper, the compass, and countless other major innovations form the technological base on which our modern societies function. But historically, China has also had a policy of isolationism. From the Great Wall erected thousands of years ago to the "Great Firewall" of today, China has long prevented both people and information from entering or exiting its domain. While China has long been a secretive and isolationist country, new evidence suggest that aliens walked among us in the ancient past, and may have been with us all the way up to today... hiding among us.

The Prototypes

Recent archaeological discoveries reveal a very different picture of what life on Earth looked like in the remote past. It was a real-life version of "Lord of the Rings," where humans shared the planet with various different types of intelligent human-like species, such as Neanderthals, Denisovans, and even hobbits. But how is it that these various hominid species developed separately in isolated pockets of the globe? And why does no fossil evidence exist suggesting a slow gradual delineation from a common species? Ancient Astronaut theorists suggest these different intelligent species seem to have come straight out of the incubator, and that Earth itself may have served as an extraterrestrial laboratory. A laboratory where different human prototypes once existed--but only one species was chosen to survive. Is mankind the result of an extraterrestrial experiment?

Space Station Moon

It was mankind's finest hour, the greatest technological achievement of the 20th Century--the Apollo 11 mission to the Moon. But the Apollo program was short-lived, and after Apollo 17 in 1972, we never went back. Could it be that we encountered something--or someone--on the Moon? Did the Apollo astronauts witness more than NASA wants us to know? The Moon is the most visible celestial body in the night sky and is essential to life on Earth. But what if the Moon is not the natural object we believe it to be? Unidentified lunar objects in NASA photography may point to extraterrestrial structures on the moon, and possibly evidence of what lies beneath the surface. Some Ancient Astronaut theorists have even suggested that the Moon is actually an artificial object, placed in its current position by otherworldly beings thousands of years ago.

Russia's Secret Files

Russia is a vast country, spanning over 6 million square miles of some of the most rugged terrain on Earth, much of which is uninhabited and largely unexplored. It is also the home of 'cosmism' -- a belief that human civilization originated in the cosmos and is destined to return to space. But many believe the rise of communism led to a wall of secrecy surrounding ancient and modern extraterrestrial contact in Russia. Ancient astronaut theorists suggest that otherworldly visitations predate the establishment of the Russian nation, and point to the ancient settlement at Arkaim as evidence--a centuries-old megalithic site that, like Stonehenge, is oriented along astronomical lines. In addition, tiny metal coils and springs recovered 30 feet beneath the Ural Mountains may indicate the presence of advanced technology on Earth thousands of years ago.

Beyond Roswell

The U.S. military has long denied that the infamous 1947 Roswell crash was anything other than a weather balloon, but FBI files released in 2011 include a memo to J. Edgar Hoover regarding the recovery of not one, but three "flying saucers." Could the U.S. government really have extraterrestrial crafts in their possession? Ancient Astronaut theorists say yes, and claim that Roswell is just the tip of the iceberg. Over a dozen other UFO crashes were reported all across the world around the same time as Roswell, and it is rumored that the wreckage from these incidents was retrieved and hidden away at secret military bases like Area 51 in Nevada, Kapustin Yar in Russia, Pine Gap in Australia, Rudloe Manor in England, and even in the remote hills of China. But if true, what happened to these alien spaceships?

The Returned

Thousands of people from every part of the world have reported being abducted by aliens, including even a world leader--President Kirsan Ilyumzhinov of the Russian Republic of Kalmykia, who announced in 2007 that he had been taken aboard an extraterrestrial ship. Could the alien abduction phenomenon be true? But if so, why are people being taken? And perhaps more importantly--why are they being returned? Stories of human abduction by otherworldly entities can be found in mythologies dating back thousands of years, and the abductees often return to Earth with new knowledge or instructions for mankind. In modern times, researchers of alleged alien abductions have found extraterrestrial objects implanted just under the skin, strange patterns in genetic mutations, and knowledge of entire alien languages from abductees. Is it possible that extraterrestrials are secretly manipulating mankind through these abduction events?

Aliens B.C.

Enormous manmade caves... Unexplainable structures... And underwater discoveries that challenge everything we know about the past...Is it possible that an advanced civilization inhabited Earth thousands of years ago? And if so, were they human, or something out of this world? Modern archaeologists are continuously unearthing artifacts and sites that defy the conventional timeline of human history. Throughout the world we find megalithic stone monuments that are attributed to mysterious ancestors, strange humanoid figures that date to pre-historic times, and evidence of ancient underground shelters hewn out of solid rock. Could it be that a sophisticated culture existed on here Earth--thousands and even tens of thousands of years earlier than we believe? Could the stories of a time when gods and otherworldly beings inhabited the planet be more than just mythology?

NASA's Secret Agenda

When German aerospace engineer Wernher von Braun joined the U.S. military and space programs after World War II, he quickly became one of the foremost scientists credited with developing the ballistic missile, the first American satellite and the enormous Saturn V rocket that enabled man to reach the moon. Von Braun's bold predictions that we would explore Mars and build a space station have become reality. But how is it that von Braun--whose contemporaries included such scientific geniuses as Nikola Tesla, Robert Oppenheimer, and Albert Einstein--was so far ahead of everyone when it came to rocketry? Did he have secret information collected by the Nazi party during WWII--or access to advanced technology recovered from the alleged UFO crash in Roswell, New Mexico in 1947? Or is it possible that the greatest rocket scientist the world has ever known found his inspiration not on our world, but another?

Aliens and Robots

Incredible strength... Superior intelligence... And even the ability to reproduce. In the 21st century, robots are being programmed to do everything from performing surgery on humans--to exploring other planets. And humanoid robots are rapidly reaching a level of sophistication that was thought to exist only in science fiction. But what are the implications of creating robots that are increasingly intelligent and independent? Is the obsession with creating counterfeit humans really pointing the way to mankind's future... or to its past? Greek stories dating to 2000 B.C. tell of the god Hephaestus creating robots to build weapons, as well as the bronze giant Talos. In Egypt, the Pyramid Texts say that the god Osiris was dismembered, then reassembled and brought back to life just like a machine. If sophisticated robots really did exist in the ancient world--what function did they serve? Who built them? And what happened to them?

Dark Forces

Good and Evil. Light and Dark. God and Satan. In nearly every culture there are stories of opposing forces at work here on Earth--forces of a supernatural or otherworldly nature. Could these forces really exist? And if so, what is the true nature of the dark forces? Throughout history, there have been individuals accused of being in league with agents of darkness. The infamous mad monk Rasputin believed he served as a conduit for an otherworldly realm, the Nazi SS were said to have tapped into dark powers through ancient symbols, and famed occultist Aleister Crowley claimed to have summoned a non-human entity through the use of dark magic. Is it possible the entities these men claimed to be in touch with were, in fact, extraterrestrials? And might humans serve as the pawns in a cosmic battle between the forces of light and dark?

The Alien Evolution

Ancient Astronaut theorists have suggested that many of the divine beings depicted in cultures throughout the world are not really divine--or mythological--but instead reflect extraterrestrial visitations that our ancestors did not understand. If true, what can account for all the different types of beings that are depicted, from anthropomorphic birds and reptiles, to gods with blue skin to multi-limbed humanoids? Might there have been numerous alien species inhabiting Earth? Could the accounts given by modern day alien abductees be evidence that these otherworldly entities continue to visit Earth to this day? And is it possible that they all have a common ancestor? In 1928, archaeologist Julio Tello discovered the Paracas skulls of Peru--elongated heads with cranial volumes at least 25% larger than the largest known human skulls. Some believe that these remains are of extraterrestrial origin.

The Other Earth

Billions of dollars have been spent in our quest to find an "other Earth." Since the launch of the Kepler Telescope in 2009, scientists have identified thousands of planets capable of supporting life. Is it possible that this discovery finally answers the age-old question: "Are we alone in the universe?" Could it be that just as we seek out other habitable planets, advanced extraterrestrials from distant galaxies did the same with Earth in the remote past? Throughout world mythologies, there are tales of beings from the stars coming down to Earth. The Dogon tribe in Africa believes their gods came from the Sirius star system. The Maya associated their gods with the Pleiades star cluster. And according to the Hopi tradition, life itself was seeded by celestial beings. Ancient Astronaut theorists propose that not only has our planet been visited by extraterrestrials, but that they are responsible for our very existence.

Creatures of the Deep

In August of 2014, Russian cosmonauts aboard the International Space Station discovered something incredibly unexpected covering parts of the windows--living sea plankton. If sea life can thrive in space, might the reverse be true as well? Might there be alien life forms that inhabit our seas? Throughout history, there have been tales of strange creatures hiding in Earth's waters. While many discount stories of sea monsters as purely mythological, it is estimated that Earth's oceans are home to between 700,000 to one million species--and shockingly, two-thirds of those species still remain unknown. Considering the recent discovery that some sea life can survive in outer space, is it possible that tales of giant creatures like the Kraken and The Loch Ness Monster are evidence of extraterrestrial entities taking refuge beneath the seas?

Circles from the Sky

Over 10,000 crop circles have been reported worldwide, appearing in 50 different countries, and nearly every continent on Earth. These strange designs pressed into crop fields range from simple circles to elaborate pictograms thousand of feet long. The phenomenon has been associated with scientific anomalies, strange lights, and even UFO activity. But critics say that they are all part of an elaborate hoax. But are they? Crop circles have been making modern headlines since the 1960's, but their history can be traced back hundreds--if not thousands of years. The designs themselves often contain encrypted messages and complex mathematical, geometric, and astronomical equations that perplex our top mathematicians and scientists. Ancient Astronaut Theorist, Giorgio Tsoukalos travels to England to meet with researchers and scientists to investigate the phenomenon both on the ground and in the lab to find out what we haven't been told.

The Alien Wars

On March 19th, 2002, Gary McKinnon was arrested for hacking into 97 Pentagon and NASA computers over a 13-month period, in what authorities call the "biggest military computer hack of all time." McKinnon claimed that he found evidence of a secret American space fleet, by way of a list of dozens of "non-terrestrial officers" and their assigned spacecraft, replete with USSS (United States Space Ship) monikers. Might the United States military really have a secret space program? And if so, are we preparing for a space-based war with other nations... or other species? Ancient Astronaut theorists suggest that there are numerous factions of alien races with competing agendas visiting Earth, and that there is evidence they have been in conflict with each other for thousands of years. According to these theorists, there is evidence that these wars actually took place here on Earth in the distant past--not between gods, but between extraterrestrial visitors.

The Divine Number

In numerous sacred traditions, the number 12 holds a divine significance; it can be found repeated in ancient architecture, groups of 12 wisdom keepers and even the latest scientific principles.

The Lost Kingdom

According to the earliest Tibetan traditions, hidden high in the Himalaya Mountains is a kingdom of the gods--Shambhala. Is it possible that this mystical realm truly exists, and can be reached through ancient practices designed to access other dimensions?

The Galactic Keyhole

The mysterious symbol of the keyhole exists in mystic texts, sacred architecture and ancient artwork found all over the planet; exploring if this cryptic shape represents a profound connection to the cosmos.

Giants of the Mediterranean

Ancient cultures recorded stories of enormous beings that descended from the sky; exploring if massive megalithic structures and reported discoveries of towering human-like skeletons reveal that the world was once inhabited by giants.

The Forbidden Bible

Rebellious angels, giant hybrid beings, and humans taken up to a heavenly realm above the Earth; examining the possibility that The Book of Enoch was stricken from the Bible because it documents humanity's extraterrestrial origins.

William Shatner Meets Ancient Aliens

In this extraordinary two-hour special, Shatner will bring thought-provoking questions to the leading experts of the show. Ancient Astronaut theorists Giorgio Tsoukalos, Erich von D niken, David Childress, William Henry and Linda Moulton Howe will be joined by former British Ministry of Defense investigator Nick Pope, rocket scientist Dr. Travis Taylor, theoretical physicist Dr. Michio Kaku, and religious history experts Rabbi Ariel Bar Tzadok and Reverend Michael Carter. They will explore everything from human origins to groundbreaking archaeological finds, new understandings of the cosmos and the profound possibility that we are not alone in the universe.

Impossible Artifacts

Throughout the world, ancient objects have been found that leave archaeologists at a loss. Could these impossible artifacts suggest that advanced--and perhaps even extraterrestrial--civilizations existed on Earth thousands of years before our own?

The Space Travelers
