Just something I've thought about before. Assuming, of course, that the universe works perfectly well without a Creator (as I do), a question springs to mind: is the belief in some almighty diety, no matter what diety is it, somehow written into our DNA? Did humanity go through an evolutionary bottleneck that conferred an advantage on those with faith? Certainly, shared belief would help a community stick together and grow, but is it really a necessity for reproductive success? Every other critter on the planet seems to get along just fine without making sacrifices or chewing on stale crackers. There are no Jewish meerkats (not to single out the Jews, that's just a funny phrase). So what is it about humans that makes them, so often, default to religion? It's certainly not utilitarian. If anything, it gets in the way of natural processes.
But it's hard to deny that faith is a gigantic factor in what makes us human. Many humans may not be religious, but will awknowledge a "higher power," abstract though that term may be. But why? Why is the the natural world not enough? At what point did mankind begin shouting at the sky, and why? What advantage does (or did) it confer?
