It's puzzling, to say the least, how domains like philosophy of mind battles the hard problem of consciousness, how we're able of abstract thinking and phenomenal experiences, and other domains of human thinking take it so lightly as 'humans started to think abstractly x thousands years ago'. Just because we see products of abstract thinking starting some point in time says absolutely nothing about how abstract thinking is working. It's not like since bones evolved, abstract thinking must have evolved too. Abstract thinking, and all things consciousness, is something evolution must account for to stand as a scientific theory of life on Earth. So far, consciousness is a big black hole in the theory, IMO.
