Most people are familiar with the biblical story of a worldwide flood, where God destroyed all life on earth except the family of Noah and the animals that they boarded on an ark.
Scholars of ancient writings from Mesopotamia (now Iraq) point to texts written thousands of years before the bible that describe a flood and say that the bible story comes from those stories.
Others like archaeologist Jeff Rose say these pre-biblical stories have merit because the destructive forces of water in a once tropical region in Iraq, considered by some to have been the Garden of Eden, might have inspired the biblical story of Noah's Ark and the great flood. Dr. Rose believes that a massive flood once swallowed a landmass as big as Great Britain, created the Persian Gulf and sent tribes of Neolithic people into constant retreat from the ever-rising waters.
The documentary, Diving Into Noah's Flood, will air January 5, at 8 PM EST, on the National Geographic Channel.
