Religion was invented to keep the human race from self destruction.

We all have enough intelligence to ask the big questions like .... is there a god ? Are we alone in the universe ? Where did we come from ?

Yet we don't have enough intelligence to enable ourselves find the answers. And that's not good because as a race, humans don't like that kind of uncertainty. It causes us to become unstable and ask dodgy questions like ... why bother ?

In steps religion to give us something to believe in or hope for, so we don't all go mass crazy.

Religion. The biggest and greatest band aid on the frabic of world society ever.
