You can't disprove God because you can keep changing the definition. If I define God as the culmination of everything in the universe, you can't really disprove that.
If you disagree with me, then I can just keep changing the definition of God!
Surely the reason you can’t disprove God is because you can’t leave the universe. Since it isn’t possible for us to know what is outside of our universe we can’t prove or disprove a god’s existence.
The god argument can't be contradicted because it's not based on logic. People can just make up rules for their gods, and they usually don't care if those conform to reality or logic as we know it.
E.g. I can just say that logically disproving my god is a proof of its godhood, because it defies and is beyond human understanding. That's just not something you can argue about.
Assuming you are sarcastic - I agree wholeheartedly.
Look up The Invisible Dragon anecdote by Carl Sagan (in his Demon Haunted World book), or for more serious people - Falsifiability principle by Karl Popper, If you haven't already.
