The Black Sea Deluge Hypothesis posits that around 7,500 years ago, the Mediterranean Sea breached the Bosporus Strait, causing a massive influx of water into the Black Sea. This event transformed the Black Sea from a freshwater lake into a saltwater sea, resulting in a dramatic rise in water levels. This rapid flooding would have submerged large areas of land, displacing human settlements along the coastline. The catastrophic nature of this event is believed to have been preserved in the oral traditions of ancient cultures, leading to the creation of flood myths, such as those in the Bible and the Mesopotamian epics like the Epic of Gilgamesh. Archaeological evidence, including submerged prehistoric settlements and shifts in the Black Sea's shoreline, supports the idea of this sudden and profound flooding event. The Black Sea Deluge is considered a key historical event that likely influenced the development of various ancient flood myths across the Near East and beyond.

But that's not the flood in Genesis. Not even close to it, for instance in Genesis the land is flooded and then the waters recede and the land comes back, whereas the Black Sea is still a sea.

You're just pointing at a flood and saying it must be the origin of a story of a flood, but there's no basis for it.

And where did Noah Land after the flood?

Right. Mount Ararat

What is the significance of that to you? Mount Ararat doesn't stick out of the sea.

Are you saying that the ark left the flooded Black Sea basin, flew through the air, and landed on a mountain many kilometers from the sea? That seems like a stretch to fit a hypothesis.

"many kilometers" Dude, it does not get much closer than that. But you are right, he did not land in Istanbul.

It's 300 kilometers away and the Black Sea isn't even the closest large body of water to it.
