Do you believe in god? If you do, why do you believe? (give a few reasons)
Why are you looking for other people's reasons for believing in God? It's a very personal belief.. I mean you can gather as many reason as you want and not be convinced of its existence.
I used to be an agnostic.. still prefer that position socially, as God's existence can neither be proven nor disproven.
