Yes, I am familiar with the cave paintings. No doubt they were made by hunter-gatherers. I am not impressed that people made such art tens of thousands of years ago, because they were biologically similar to modern human. I wonder why much older art is not found. Graham presented an interesting theory about invention of psychedelics and emergency of cave art, but I do not necessarily buy it.
