Aliens and Mega-Disasters-S4/E4

There are numerous historical, religious and mythic accounts of ancient civilizations being wiped out by volcanoes, earthquakes, floods, and meteors. Did god, or nature bring about such disasters? Or is it possible that celestial beings had a hand in the ancient world's catastrophic disasters?

The Greys-S4/E3

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?

Aliens & Superheroes-S6/E28

From the beginning of recorded history, humans have told stories about beings with super-human strength, super-sonic speed, and supernatural abilities. The ancients had heroic tales about Zeus, Thor, and Hanuman while today we have superhero stories about Superman, Batman, and Spider-man. Mythologists say these epic stories resemble each other because they may have all come from a common set of oral legends created eons ago by our earliest ancestors. But might there be another, more otherworldly reason that the world's heroic myths are so similar? Is it possible, as many Ancient Astronaut Theorists contend, that these stories are actually based on extraordinary– and possibly extraterrestrial–beings that lived on Earth in the distant past?

The Doomsday Prophecies-S4/E2

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?

The Mayan Conspiracy-S4/E1

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?
