Zecharia Sitchin (July 11, 1920 – October 9, 2010)
an author of a number of books proposing an explanation for human origins involving ancient astronauts.
Sitchin attributed the creation of the ancient Sumerian culture to the Anunnaki, which he stated was a race of extraterrestrials from a planet beyond Neptune called Nibiru.
He asserted that Sumerian mythology suggests that this hypothetical planet of Nibiru is in an elongated, 3,600-year-long elliptical orbit around the Sun.
