You are wrong about that. There is a way to prove the existence/nonexistance of god. I have PROVEN that he doesn't exist. Science has never seen him. All the outrageous claims of supernatural ability by the likes of Jesus or Elijah or Muhammad are all unsubstantiated. The Amazing Randi when he was alive (and Houdini before him) debunked anyone and everyone who claimed to possess any sort of power like that.
So, what's the real issue here? It's that the believers believe all this garbage. The problem certainly isn't with the atheists or scientists because they've got their heads screwed on right.
Therefore, the point of this post and nearly all of the my other posts is the same--to wake people up to the fact that their almighty god in the sky is a fantasy and shouldn't figure in their day to day lives or decisions.
