Zecharia Sitchin

From RationalWiki

Zecharia Sitchin is a complete crank who believes in a twelfth planet that created all life on earth called Nibiru. It is apparently a "yo-yo" planet that only shows up so often, or something. It is also responsible for the asteroid belt.

He also believes that a missile from Phobos shot down a Soviet spaceship. All of this is supposedly found in a prophecy written by the ancient Sumerians.

Somehow, he is convinced that he is moments away from being recognized as the most important scientist of all time.
