Really powerful being. Creator? Lover? Many religions interreupt him differently.

Some tautology arguments

There are indeed many "counterarguments" to Non-God that basically assume that there is a God.
For instance, the idea that God is above all logic. It basically eliminates all forms of debate.
Or by saying that the Bible is true and thus God exists. And who says the Bible is true? God. However you cannot ignore the fact God and the Bible were lying which would prevent the loop from even being true in the first place.
Or the idea that there has to be something that caused the universe to exist from nothingness. What if it was the Big Bang (which usually isn't called a God at all?)
However, this does not mean all arguments for God's existence are invalid. Rather I cannot verify anything! The reason is that the God v.s. No God debate has existed for so long precisely because there is no way to verify and that it is metaphysical so even morals cannot really find any semblance of an agreeable solution. Not that that is a bad thing though, it's a pretty interesting point of conflict among humans: was there a divine power?
