How can we believe that God brought the Flood to punish mankind for his evil sins - if God is a spiritual being, he would never have needed to use a Flood. The Flood is a prime example of how an actual physical event can be disguised by a heavy emphasis on monotheistic symbolism.
The story can be gleaned from ancient texts which pre-date the Bible. These are found in clay tablets from the excavation of Mesopotamia and brings to light the amazingly advanced civilization of Sumer.
From almost every culture around the world there emerge more than five hundred strikingly similar legends of a great Flood. These legends all share a common theme - of mankind being swept away with the exception of one man and his family who survived. The West generally knows the survivor’s name as Noah, but to the Aztecs he was Nene, whilst in the Near East he was Atra-Hasis, Utnapishtim or Ziusudra.
The Atra-Hasis epic clarifies the role of the Biblical “God” as “they” rather than “He”. Furthermore, this account, inscribed in detail on tablets states that “they” did not bring it about deliberately. Instead, it was resolved in the council of the gods that the coming Flood, which the gods were powerless to prevent, should be kept secret from mankind.
The roles of the gods (the Annunaki or Nefilim or “descended from heaven to earth”) in the Mesopotamian Flood stories are Enlil, the Biblical “Lord” to whom mankind has become a nuisance, wishes to see them destroyed. His brother Enki, who was personally involved in the creation of the first Adam , is sympathetic towards man and habitually antagonistic towards Enlil. Despite being pressurized into taking an oath of secrecy, Enki decides to warn one loyal follower and his family of the coming deluge. The chosen man is a priest from the city of Shuruppak (the city of Enki’s sister Ninharsag), whose name in the Akkadian language is Atra-Hasis, meaning “Exceedingly Wise”. It is worth noting that exactly the same meaning is applied to the hero Utnapishtim in the Flood account of The Epic of Gilgamesh.
The god Enki, also known as Ea. speaks to Atra-Hasis from behind a reed screen, a detail which is also found in the original Sumerian text, where the hero is named ZI.U.SUD.RA. Detailed instructions are given by Ea for the construction of a submersible ship. The Epic of Gilgamesh provides a dramatic and vivid account of the final preparations, when the hero is told to watch for the departure of the gods themselves.
The Sumerian scribes state repeatedly, that the Flood was caused in 11000 BC by Nibiru the planet from which the “gods” came to Earth. The Earth’s waters would have been pulled to one side by gravitational attraction, causing an enormous bulge towards Nibiru as it passed Earth during the encounter.
