This 6000 year old seal depicts Sumerian gods (The Anunnaki) teaching the Sumerians about the solar system. The Sumerians where the first known civilization to accurately locate each planet in the solar system. Not only did they accurately list the planets in the correct order but also described what color each planet was and that they orbited the sun. They also described another planet (Nibiru) which was the home planet of there gods, which had an oblong orbit around our sun. Nibiru is believed to be orbiting our solar systems sister star, which orbits our star every 3600 years.
