Isn't it interesting that every single person feels the need to believe in a god or higher power of some sort? Since it's so universal believing in a god must have given us an advantage to help keep us alive and the people who didn't feel this need must have perished so their genes didn't get passed on. It seems irrelevant whether there actually is a god or higher power, the advantage seems to come from just believing that there is. It's the same with the universal reaction we all have to "scary" noises. We probably first heard these sounds when wind blew through trees and since wild animals can hide in trees the people who found the noise of the wind howling through the them scary and therefore moved away from them survived to pass on their genes (and therefore passed on this fear) while the people who didn't have this fear got eaten and therefore the lack of this trait didn't get passed on. I'd be interested to hear what everyone else thinks.
