The Great Flood

S9, E8: It is a story told in more than twelve hundred cultures around the world--the gods sent a great flood to wipe out humanity for its disobedient and wicked ways. Do these numerous creation myths point to an actual deluge, one that engulfed the world and spared only a chosen few? 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 gravesite, scientists are starting to put the pieces of a very deadly puzzle together--a puzzle that some believe was created by extraterrestrial beings. Did humanity narrowly escape extinction? And are the ancient stories correct--that alien beings are the reason we survived? Ancient Astronaut Theorists believe they are--and that celestial beings are poised to save us again when another catastrophe sweeps across the Earth.
