Why do people from all genearations look for God?

To some extent, our brains are hard-wired to believe in supernatural things when we are confused about something. It's sort of a vestigial thought process that is carried over from a time long ago when we were hunter-gatherers and that sort of thinking bonded people into groups who, because of strength in numbers, were more likely to survive to reproduce. This vestigial process, like our appendix, is not needed anymore.
