This is a Presentation by the late and Great Zecharia Sitchin about his over 70 years of research.
Zecharia Sitchin (born July 11, 1920, died October 9, 2010) was an Azerbaijani-born American author of books promoting an explanation for human origins involving ancient astronauts. Sitchin attributes the creation of the ancient Sumerian culture to the Anunnaki, which he states was a extra-terrestrials people from a planet beyond Neptune called Nibiru.
He believed this planet called Nibiru to be in an elongated, elliptical orbit in the Earth's own Solar System, asserting that Sumerian mythology reflects this view. Sitchin's books have sold millions of copies worldwide and have been translated into more than 26 languages.
