Why religion exist?

I think we have religions to figure out why we are here and what our purpose in life is. We need to look to a higher power in order to do that. I feel that we need something to believe in and worship to somehow reach some kind of personal fulfillment. I don't think any religion or way of worshiping is wrong because everyone has their own set of beliefs and traditions. It gives people the hope that there is a better place afterlife. It also helps explain the unknown in the world we live in. There will still be questions unanswered but it gives people a chance to pay attention to something other than themselves.
