God has already been proven and in a number of ways. Perhaps the most compelling of which is the creation argument. Why do we have something rather than nothing? That question cannot be answered without first disregarding our most basic laws of physics. Essentially, only a God like being (or act) could get us a universe from nothing.
And there you have it: proof of God. Now watch as atheists continue to deny God even as the proof sits right in front of them.
