Humanity has a past known to us through archaeologists, anthropologists and geneticists, an age in which tools were stone, sticks and twine. People lived in small societies in a vast area that was their's for hunting game and gathering food. They were skilled at crafts but had little understanding of the world beyond what they knew through touch and sight. Everything that moved they assumed did so because of will - spirit. This put them close to the material world. They didn't differentiate between matter and spirit. Thus they might eat the flesh of a strong leader believing they were ingesting the strength of that leader. This kind of immediate improvement was their sense of progress. They lived for the day. And politically and economically they were collectivist. They prayed for the group rather than individual self.
