I don't buy that the main reason for religion or god was to control people. I think it came in as a by product. God or the idea of any god is by its very nature supernatural and superstitious. There is no proof for any god. Not one whiff of proof. The best anyone can do is to have a circumstantial argument. Irreducible complexity, Argument by design are the main two that have some small bit of weight in an argument. The rest is total BS. I feel this or that is irrelevant. IMO religion was started to explain what ignorant people did not know and or understand. Today many people who believe are lazy and do not want to look into the facts or the science. Its a sad fact but true.
Even if you do a gimme to the supreme being side and say lets for the sake of the argument say humans were created by a higher entity, what god what entity? Aliens? Allah? Christ? Zoroasterism? Or any number of tribal and lesser known gods, the gods of the Romans? Greeks? Its all BS. Until a god shows up to the world and stops playing a shell BS game and says I did this and I expect this, I say its BS. Its impossible to prove a universal Neg. so I can no more prove god does not exist then someone can prove god does exist.
