Nibiru

Nibiru (called "the twelfth planet" because, it is claimed by the Sumerians' gods-given conception of the Solar System counted all eight planets, plus Pluto, the Sun and the Moon) was the home of a technologically advanced human-like extraterrestrial race called the Anunnaki in Sumerian myth, who Sitchin states are called the Nephilim in Genesis. He wrote that they evolved after Nibiru entered the inner Solar System, and they first arrived on Earth probably 450,000 years ago, looking for minerals, especially gold, which they found and mined in Africa. Sitchin states that these "gods" were the rank-and-file workers of the colonial expedition to Earth from planet Nibiru.

Enki (the Sumerian god of water and human culture) suggested that to relieve the Anunnaki, who had mutinied over their dissatisfaction with their working conditions, that primitive workers (Homo sapiens) be created by genetic engineering as slaves to replace them in the gold mines by crossing extraterrestrial genes with those of Homo erectus.[8][9] According to Sitchin, ancient inscriptions report that the human civilization in Sumer, Mesopotamia, was set up under the guidance of these "gods", and human kingship was inaugurated to provide intermediaries between mankind and the Anunnaki (creating the "divine right of kings" doctrine). Sitchin believes that fallout from nuclear weapons, used during a war between factions of the extraterrestrials, is the "evil wind" described in the Lament for Ur that destroyed Ur around 2000 BC. Sitchin states the exact year is 2024 BC.[10] Sitchin says that his research coincides with many biblical texts, and that biblical texts come originally from Sumerian writings.
