Here's a documentary special discussig Zecharia Sitchin's studies in ancient Sumeria and their writings on human origins. According to Sitchin, the Ancient Sumerians believed humans to be a hybrid genetic creation of a species they called the Anunnaki who inhabit a planet called Nibiru (modern science refers to this as Planet X). Nibiru is a distant planet which orbits our very own sun on a massive eliptical orbit returning every 3,600.
