Black Sea deluge theory

Pitman, along with Columbia colleague Bill Ryan, published evidence in 1997 that a massive flooding event greatly expanded the Black Sea very quickly around 5600 BC. This was published as ''Noah's Flood: The New Scientific Discoveries about the Event that Changed History'' in 1998, in which the authors argued that the deluge could be linked to mythical flood events such as

Noah's Flood The Genesis flood narrative (chapters 6–9 of the Book of Genesis) is the Hebrew version of the universal flood myth. It tells of God's decision to return the universe to its pre- creation state of watery chaos and remake it through the micro ...
