Why are they all so obsessed to prove the existence of god? If you believe in it than keep it to yourself, because there is no way to prove it. It's 2011 you should have a better understanding of the world. If you are so obsessed with having people believing the same god you do, go to church and keep out of the public. That's what they were made for.
Religion is like a Penis, you shouldn't whip it out in public and you shouldn't shove it down your child's throat.
