Boundary Limitations for the Existence of God

If god exists , then its existence is only possible within the two boundary limitations and they are:

(a) inside the human brain, or

(b) outside of this universe.

There is not any probability for the existence of god between "outside the human brain" and "inside of this universe".If you find any people believing the nature as a god then either he/she is being fooled or he/she is trying to make other fool.
