- The problem with this theory is that you require proof from any believer. One might believe the sky is blue....he is under no similar obligation to prove it to you. One might believe the sun rises in the east - and while you might call such fact empirical, the believer is under no obligation to prove it to you. The beauty of belief is that it can exist with or without you, and for nearly all, proof to you is of zero import. The Atheist failure is not one of proof or lack thereof. It is one of arrogance.
