What religion actually says God lives in cloud???. And while i dont know that my interpretation about my God is true, i know that interpretation about a God living on clouds is false. Is it that hard to understand?? If i can PROVE that there is no God living in the clouds than that interpretation of God is false. And since we know that no one lives in the clouds, we know 100 percent that is false.

How exactly can you prove that when no evidence for gods existence actually... exists? It's all subjective as the actual concept of god is not set in stone.
