What is the point of what? Faith? Belief?
I've heard it said that religion exists because people can't cope with both being alive and having to die. I agree wholeheartedly with what Og said. Religion provides focus and purpose and meaning for billions of people.
I would say faith is integral to belief. As you said lc, how would someone deal with knowing, beyond a shadow of a doubt, how massive the universe was and how small they were, especially if they had no form of deity to provide meaning? I think belief stems from personal insecurity, hence an overabundance of faith. Belief requires suspension of disbelief; it is because of people's inability to cope with the probable reality of our existence that creates the need for belief, and in turn religion.
An awful lot of pointless words to say I agree.
