Planet of the Crossing: Nibiru or Planet X

The term "Nibiru" comes from the Sumerian cuneiform tablets and writings dating 5,000 years old. The term Nibiru means "Planet of the crossing", and it's cuneiform sign was often a cross, or various winged disc. The Sumerian culture was located in the fertile lands between the Euphrates and Tigris rivers, at the southern part of today's Iraq. It was the home of a technologically advanced human-like alien race, the Anunnaki of Sumerian myth, who survived and later came to Earth. They came in search of gold particles used for their reflective properties (recognized even today by Nasa who plate various objects including astronaut helmet eyeshields) to place in their atmosphere. According to Sitchin, they subsequently genetically engineered our species, originally as slave workers to work in their gold mines, by crossing their genes with those of Homo erectus.
