Coming from outer space, the planet crashed through the solar system, pushing Pluto onto its current orbit and cutting one planet in half, creating Earth out of one side and the asteroid belt out of the debris. Sitchin gets his claims from his interpretation of Sumerian myths as factual accounts.
While on Earth, the inhabitants of Shar, which Sitchin calls Nefilim, genetically engineered humans as a slave race to help with mining.
was an author 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.
The gods come from above and travel to Earth, walking among the people.
Sitchin interprets the Sumerian myths as being factual accounts of alien beings from an extra planet in Earth's solar system that came to Earth 450,000 years ago to mine for gold and other rare minerals.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.Sitchin's books have sold millions of copies worldwide and have been translated into more than 25 languages.While working as an executive for a shipping company, he taught himself Sumerian cuneiform and visited several archaeological sites.Similar to earlier authors such as Immanuel Velikovsky and Erich von Däniken, Sitchin advocated hypotheses in which extraterrestrial events supposedly played a significant role in ancient human history.Based on a Sumerian origin myth, he recounts how the arrival of this planet formed the solar system as we know it, and he credits the Nefilim for advancing humanity and also for the stories of the Great Flood.Sitchin gives a history of the archeological investigation into ancient societies, tracing the known culture of ancient Greece back to earlier cultures, finally arriving at the earliest known civilization of Sumer.Sitchin states that when struck by one of planet Nibiru's moons, Tiamat split in two, and then on a second pass Nibiru itself struck the broken fragments and one half of Tiamat became the asteroid belt.The second half, struck again by one of Nibiru's moons, was pushed into a new orbit and became today's planet Earth.According to Sitchin's interpretation of Mesopotamian iconography and symbolism, outlined in his 1976 book The 12th Planet and its sequels, there is an undiscovered planet beyond Neptune that follows a long, elliptical orbit, reaching the inner solar system roughly every 3,600 years.This planet is called Nibiru (although Jupiter was the planet associated with the god Marduk in Babylonian cosmology).
