S01 E01Apr 21, 2010
The Evidence Apr 21, 2010 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?
S01 E02Apr 28, 2010
The Visitors Apr 28, 2010 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.
S01 E03May 5, 2010
The Mission May 5, 2010 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.
S01 E04May 19, 2010
Closer Encounters May 19, 2010 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?
S01 E05May 26, 2010
The Return May 26, 2010 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.
S01 E07May 18, 2010

S02 E01Oct 29, 2010
Mysterious Places Oct 29, 2010 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?
S02 E02Nov 5, 2010
Gods & Aliens Nov 5, 2010 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?
S02 E03Nov 12, 2010
Underwater Worlds Nov 12, 2010 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?
S02 E04Nov 19, 2010
Underground Aliens Nov 19, 2010 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.
S02 E05Nov 26, 2010
Aliens and the Third Reich Nov 26, 2010 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?
S02 E06Dec 3, 2010
Alien Tech Dec 3, 2010 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?
S02 E07Dec 10, 2010
Angels and Aliens Dec 10, 2010 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?
