For some reason queedo, you are super-sensitive about your views... perhaps you've had other views enforced on you for a very long time, and only recently have been able to make a conscious decision regarding your beliefs?
(don't mind me, just my pathetic attempt at analysis ^^)
In answer to your original question, because its, well, nice, to think that a supreme being has nothing better to do then to sit around and watch your life, and respond to your prayers. I can understand how people can derive solace and joy from religion, even though i am not a religious person in the conventional sense.
Its kinda hard to be when you believe that the supreme power in the universe, and therefore "God" is Chance.
PS - chavos: I really hate being pedantic, but.. um... the basis of calculus IS geometry. Its technically possible to find any result obtained using calculus via geometry, provided you are capable of measuring a miniscule quantity
