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?
- E2
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.
- E3
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.
- E4
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?
- E5
The Return
There is evidence that suggests we experienced 20th century alien contact. In 1942, the Battle of Los Angeles involved the US military and Air Defense allegedly fighting a UFO. WWII Allied Air Force planes were buzzed by balls of light that some think could have been extraterrestrial. And the alleged crash of a flying saucer in Roswell, New Mexico in 1947 propelled the world into the age of UFOs. For decades, some people have been searching for the sounds of extraterrestrial intelligence, while others have been sending messages out into deep space. What would happen if aliens answered... or came calling? What protocols exist to determine who would speak on behalf of mankind, and how might we communicate? What happens if they return? Some believe they already have.

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?
- E2
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?
- E3
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?

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?
- E2
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?
- E3
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?

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?
- E2
The Doomsday Prophecies
The Maya created the most sophisticated calendar systems in the ancient world, and according to many scholars their Long Count Calendar will come to an end on December 21, 2012. What does this mean for mankind? Some researchers believe it will usher in the return of Bolon Yokte--a mysterious god associated with creation and war. Could this god actually be an extraterrestrial as some ancient astronaut theorists believe? Other scholars believe the end of the calendar will bring about a series of catastrophic events that may threaten the very existence of mankind. They point to a rare galactic alignment that will coincide with the end of the Mayan calendar as proof of an impending geological catastrophe. If these doomsday prophecies prove to be true, will it mean the end of the world as we know it? Or could it reveal some profound truth about the origins of the human race?
- E3
The Greys
Who are the beings with big heads and giant eyes that seem to have been visiting our planet for millennia? Known by researchers as the "greys," these mysterious beings have been depicted in rock-art and carved stone figures throughout the ages and all over the world. Who are they, what planet do they come from, and what do they want?

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.
- E2
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?
- E3
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?
- E4
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 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?
- E2
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?
- E3
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?

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?
- E2
Aliens in America
Strange rock carvings from 8,000 B.C. Unexplained sightings in the new world. And a frightening anomaly plaguing the American West. Is there more to America's past than is found in our history books? Could the mysterious stories and relics found throughout the United States be evidence of extraterrestrial contact in the distant past? In 1909, the Phoenix Gazette reported the finding of a strange man-made cave filled with ancient objects and mummies. Could there be a connection between the mysterious cave and the legend of Native American ancestors called "Star Beings?" Strange lights and unexplained weather anomalies were documented throughout colonial America. Is there evidence that early American settlers had close encounters with extraterrestrial entities? Could UFO sightings and reports of alien contact be part of America's untold history?
- E3
The Star Children
On every continent, there are stories of children who "stand out" for their strange abilities and advanced knowledge. They are said to have knowledge of things they shouldn't or couldn't know. The ancient Greeks, Egyptians and many other cultures have legends about exceptional children who are the offspring of humans and the gods. Could the stories be more than mere myth? Is it possible there are children being born on Earth today who can access their alien DNA--a connection that endows them with special gifts and the power to transform society?

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?
- E2
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.
- E3
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?

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?
- E2
Mysteries of the Sphinx
The Great Sphinx in Giza is the largest and most studied monolithic sculpture on Earth, yet it remains one of humanities greatest mysteries. This ancient monolith defies explanation, pre-dates our earliest known civilizations and may hide the secrets of our very origins. While mainstream archeology theorizes that the Sphinx was built around 2500 BC, geological evidence suggests it is much older. If this is true, then who--or what--created the Sphinx? Researchers are now proposing the existence of a second, twin Sphinx on the Giza Plateau. If so, has it been deliberately hidden from mankind? The face of the Sphinx is believed to represent Egyptian pharaoh Khafra, yet the size and proportion of the massive carving suggests the head has been altered. Could the statue have originally represented an otherworldly being that came to Earth some 10,000 years ago, as Ancient Astronaut theorists propose?
- E3
Aliens Among Us
There are those who believe that the evolution of technology is not entirely of our own making. Ancient Astronaut theorists contend that it is by extraterrestrial design that we have become so technologically interconnected--and that we are being watched by beings from beyond our world. Do stories from the ancient past hold evidence of alien overseers? The Book of Enoch describes divine entities called the Watchers descending to Earth to monitor humankind and aid in our advancement. Inca legend states that the god Viracocha created humans and taught them astronomy, agriculture and other advanced arts. The Maya civilization believed their supreme god Kukulkan taught humans writing, mathematics and science. In ancient Chinese legend, the divine ruler Huang Di introduced numerous advancements such as the wheel, weaving and writing. Could it be that our increased reliance on computers, cell phones, tablets, and the Internet is the product of extraterrestrial design?

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?
- E3
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?

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?
- E3
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 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.

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?
