Tsoukalos travels to India to further explore the Sanskrit texts, as well as the structures and technology that have stood the test of time.

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.

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.

New evidence suggests that many fabled aspects of these flood myths may, in fact, be true. From traces of a major meteor impact in the Indian Ocean, to a worldwide ash layer, and even remnants of Noah’s grave site, scientists are starting to put the pieces of a very deadly puzzle together–a puzzle that some believe was created by extraterrestrial beings.
