Human brains showed great improvement 50 - 30 k ago, and some places even older where they have found the evolution of art, and with art they believe consensus we most likely formed as will. They can not know for sure, but most likely there where good times, and they had excess energy and food, and safety, and they had also most likely discovered alcohol and psychedelics, that might helped to form their view and thoughts on the world they knew. We also know funeral rituals started as far they can prove 100k or more back. So simple symbolic rituals have been with us for a very long time. AI do not agree with me first about my speculation about use of alcohol which can not be proved, and first finds proofs 15k or so back, but I think it is high chance they discovered fermented food/fruit, and at least used that seasonally. But who really knows.
