Considering the fact that modern human fossils have been found at Jebel Irhoud, Morocco, which date back some 360,000 years…. It’s quite possible it was anatomically modern humans. Or at least extremely close.

My bet is that the age of humanity will keep getting older and older the more we discover. And as archeology starts to explore the areas covered by water (but were not covered 12k+ years ago)… our understanding of human history will drastically change to include a lost civilization of modern humans in the last 100k years. A civilization that had the capacity to map the planet, had a understanding of the precessional cycle and the dimensions of the planet. As well as a vast understanding of astronomy and geometry.
