The only big bang I believe in is the one of human consciousness. It came out of nothing.
I think the gap between humans and animals is so big that any explanation is less believable than the explanation that we are visited by extraterrestrial astronauts. Why wouldn’t that be possible? If we believe now that within say 5000 years we will encounter intelligent life in space, why wouldn’t we believe that intelligent life has encountered earth first?
This site tels a lot more. I hope you respect the meaning of others. Not that you have to follow that meaning but who knows
