I really doubt there is any scientific proof to describe god existence.
Who need proofs about unicorn or flying spaghetti monster?
So true.
That's why its called a religion. That's why there are many religions. That's why there was mythology.
It's just a matter of believing, not proof-concept of existence.
I guess this caps it all, it's a matter of individual beliefs that leads us to the path we choose to stick to.
