"You really have to wonder what civilizations could have predated the Egyptions or Sumarians, but simply didn’t build with a material that lasted long enough for us to find their traces

Yeah, I read that back during the last Ice Age the Black Sea was a fresh water inland lake that was much smaller than it is today, and the Mediterannian was also much lower in water level.

Then when the Ice Age ended, the Med started filling up and then broke through and filled up what is now the Black Sea. Since civilizations tend to hug shorelines, they ought to calculate where those ancient shorelines were, and then dive down there and start checking things out.
