Gilgamesh probably goes much farther back than that. Parts of Sumerian legends probably go back to the flooding of the Persian Gulf and the breaching of the Bosporus

One needs to remember that these islands and areas of exposed continental shelf would take a period of time before they can be really habitable

@davidkelly4210 I think it depends a lot on just how we define a "civilization". Was the culture that erected, carved and buried Golbecki Tepe a civilization? I'd say so. It may or may not of had agriculture as we define it. But they certainly had some sort of social cohesion. The National Geographic Society commissioned Robert Ballard and his group to do a survey of the wrecks of Allied warships lost around the Dardanelles during the Galipoli campaign in WWI. https://www.google.com/url?sa=t&source=web&rct=j&url=https://licensing.screenocean.com/record/215989&ved=2ahUKEwjOoJWn86PwAhXbQc0KHRSPCUUQFjAnegQIKxAC&usg=AOvVaw1OSX9LOKOL4kGud0JDVlcE Finding the wrecks was no problem. It was known pretty much where the were. In addition his team also found a number of circular stone structures with a taller stone structure in their center. One immediate conclusion was that they were religious structures of some sort. That seems, at least to a layman like me, to be one of the go to conclusions about ancient discoveries. To me they might have had a different purpose. Could they have been some form of communal dwelling for an extended family. They were up to about 30 meters in diameter and the central pillar could well have been used to support roof beams that extended from the outer circle to the center. Doing any extended od more thorough investigation would require an underwater survey but the whole problem is that the wrecks in the area are war graves which complicates the situation. The kicker here is the area was last above sea level at least 8,000 years ago. I suspect that there are a lot of archeological sites in areas that were dry land during the last glacial maximum. I'm not saying lost cities* I'm simply saying archeological sites. In terms of the earliest civilizations. As I said above it depends on just how we define it. I'd say if you have a common culture, social organization and way of making your living a society is most of the way there. *there may be some urban sites off of India's western coast southwest of Mumbai. If so just when did they go under the waves. Plus how long was the time frame from the first dwellings made of organic materials to the first mud brick structures to working with stone. There is a lot we do not know yet.

In the past I've seen where it has been hypothesized that it was the adoption of agriculture that derailed the coming of the ice.

As the climate cooled the great tropical rain forests would shrink greatly speeding the millennium long Bantu migration from westrn into southern Africa
