Did the Noachian flood story originate in the Black Seas event?
As noted above, conservative Christians generally believe that God prevented the authors of Genesis from making any errors in writing. They believe that the Noachian flood must have happened precisely as the Bible says. The story was derived from the events of a world-wide flood, circa 2350 BCE. It was not based on a local flood of the Black Sea in the 6th millennium BCE. To many conservative Christians, the 6th millennium BCE did not exist, since they believe that the world was created circa 4004 BCE. Many mainline Christians, liberal Christians, secularists and others are open to the theory that the Genesis flood story was not based on an actual, world-wide flood.
