Do agree the Black Sea was originally an immense fresh water lake that was eventually flooded by sea water from the rising Med. Don’t agree it was the site of the Noah/Gilgamesh story. Much more likely to find the origins of the story in the Persian Gulf (another fresh water lake flooded by rising sea water). Check out the geographical location of Eden, it weren’t near the Black Sea.
Skeptics have been suggesting mundane explanations for Biblical miracles for a lot longer than a 100 years.
Relentlessly they’ve been proven wrong over and over again.
