I'm fully aware of doggerland, but so what? Given all of Africa and Eurasia, doggerland was a tiny benighted patch of lowland in a cold remote corner. I'm sure some people called it home, but I don't see any compelling reason to put a lost civilization on it 100k years ago.

There are plenty of very fertile, habitable areas in the same region that would have been just as attractive. So settlements? Sure. But surely a civilization is more than just a settlement?
