Zecharia Sitchin presents his groundbreaking interpretation of ancient Sumerian texts describing the formation of our solar system and humanity's extraterrestrial origins. The renowned author of "The Twelfth Planet" explains how 6,000-year-old Mesopotamian tablets describe a catastrophic collision between the invading planet Nibiru and another celestial body that created Earth and the asteroid belt. Sitchin details how this cosmic event allegedly trapped Nibiru in a 3,600-year elliptical orbit around our sun, bringing its inhabitants, the Anunnaki, into periodic contact with Earth. The conversation explores connections between Sitchin's translations and recent astronomical discoveries, including the controversial Hale-Bopp comet and its potential artificial characteristics. Art Bell and Sitchin examine how ancient Sumerian cosmology might explain modern UFO phenomena and the ongoing search for Planet X beyond Pluto. The discussion covers the implications of Sitchin's research for understanding human genetic manipulation by advanced extraterrestrial beings and the cyclical nature of their return to Earth. Sitchin's scholarly approach to ancient texts provides a framework for interpreting myths and religious accounts as historical records of actual extraterrestrial contact, challenging conventional archaeology and astronomy with evidence from humanity's oldest written records.
