This theory takes researchers back in time to the cradle of civilization in the Middle-East, the ancient land of Mesopotamia. The Sumerian Cuneiform tablets, uncovered in the 17th century, provide modern man with a new understanding of our history. This lost knowledge has been slow to make its way into mainstream thought and is just now beginning to air on television on both the History and Discovery Channels. Accurately decoding the complicated language of the past has taken archaeologists many decades, but fortunately today these ancient scriptures have come to light for all the public to view. The Sumerians claimed that all aspects of civilization were taught to them by the deities that were worshiped in the temples of Mesopotamia. Detailed knowledge about the Earth’s orbital plane, tilt axis, spherical shape, and precession behavior of its equinox were known by the Sumerian deities, who were also credited for the construction of the Zodiac. Contrast this detailed level of knowledge in Sumer with that possessed in Europe during the Middle-Ages.
