KJV Genesis 7:19–20 “And the waters prevailed exceedingly upon the earth; and all the high hills that were under the whole heaven were covered. Fifteen cubits upward did the waters prevail; and the mountains were covered”.
And 15 cubits is what? Maybe 50 feet, maybe less. The ice age ended. Yes, there was climate change then also. Water from the ocean broke over into what is now the Black Sea and inundated early civilization there. Other similar events happened all over the world. That is why there are legends of a great flood in other societies.
It isn't far fetched to say that an event somewhat like the Noah story happened. A farmer on the shore of the lake that became the Black Sea had a boat that he had recently built and loaded up his family and animals and survived. My family has legends and lore that go back to the early 1800s and tell of how my 3X Great grandparents eloped in Georgia and ended up in Louisiana for the 1810 census. And the older generations told me stories about that which may or may not have been exactly accurate and that was only a little over 200 years ago.
No telling how a story 2000-3000 years old could get a bit romanticized in the retelling.
