The ancient astronaut thesis, despite von Daniken being roundly discredited, remains popular. Zacharia Sitchin‘s 12th Planet and its sequels argue that the Babylonian creation epic Enuma Elish, as well as other texts including Genesis, record memories of ETs visiting Earth at an early stage of human development. These aliens, called the Annunaki, originate on a planet called Niburu which orbits the Sun on a 3,600 year orbit, and is thus unknown to contemporary science. His books have been very influential upon metaphysical conspiracist narratives.
The following videos are of a series of “documentaries” on the ancient astronaut thesis which were produced by the History Channel in 2008. 12 more episodes after the jump.
