Behind every creation, there is a creator, this is common sense and logical and doesn't consume too many brain cells to work out whether God exists or not. Human itself is a proof that God exists.
Let me tell you what's common sense: no one has heard or seen God. No one has any tangible proof. Until that's happens we'll stick to the things that are real around us. Sure, stories are nice, but for kids, to help them sleep.
No one who is mentally and spiritually blind has seen God. But many of us see Him through the goodness He does for all of us, even for the mentally blind people.
