As for religious belief, obviously many humans find it compelling, and useful, not a waste of time. It's their choice, just as ours is to post here. I obviously support their right to believe in whatever they choose, there are a lot of options out there. I know friends of mine who were pretty devout Christians found religion to be a critical part of their lives, something which they would not like to give up clearly. Most are pretty smart folks, it's not for me to decide what is silly and wasteful in their lives.
