The story that civilization started 5-6000 years ago in Mesopotamia is pretty quickly eroding away. It’s interesting to see all the new evidence for advanced technology existing much earlier than expected.
Sounds like they canoed across the narrow Straight of Gibralter with a burned out log canoe (or they put a suggestive image of it in there anyway). Hundreds of people have swum across the Straight of Gibralter, I don't think this is showing emergence of civilization necessarily if it was swimming or canoeing.
