Ancient Sumerian texts indicate that the Earth (" Tiamat ") was struck by a large planet, which moved it into its present orbit, and created the Moon and the Asteroid Belt. In his books, The Twelfth Planet and The Cosmic Code, Zecharia Sitchin outlines this "celestial battle" as described in the Babylonian text called Enuma elish. The planet "Marduk" (the Sumerian " Nibiru "), as it came into the solar system on its clockwise elliptical course, struck Tiamat, which was moving in its ordained counterclockwise orbit. One of Marduk's satellites struck Tiamat first, followed by two more of Marduk's moons. Then Marduk itself, an enormous planetary body, struck Tiamat, smashing one half of the planet into pieces, which became the Earth's Moon and the "Great Band" (Asteroid Belt). The other half of the planet, which was struck by a smaller moon of Marduk, was moved into a new orbit, along with a chunk of material which became its moon. The new planet was then called "KI," meaning "cleaved one." The Earth's original moons were dispersed, many changing the direction of their orbits.
Sitchin has also written in Divine Encounters, the planet where God the creator resides is referred to in the Bible as Olamin, the plural of Olam. The meaning of "olam" in the ancient world was a measure of a really long time, specifically related to the span of time between the periodic disappearance and reappearance of the planet Marduk/Nibiru on its vast 3,600 year elliptical orbit. The domain of Olamin was described as a kingdom which encompasses many worlds. According to Robert Temple, in The Sirius Mystery, the Dogon tribe of Mali call this planet "the egg of the world," and they say it is the origin of all things. They say of this planet that it is "the center of all things and without its movement no other star could hold its course." They say it is made of a heavy metallic compound called "sagala." The Sumerians also wrote that this planetary "god," Nibiru, "remade our solar system and remakes the Earth on its near passages."
