Bob Ryszkiewicz, you make a good application of Schrodinger's Cat! It is both alive and dead.

I have made the point that any "proof" of God is doomed to fail; The God of Biblical fame, that is. It is PURELY a faith proposition. Mrrzy's odds are a little off too. Mathematically or in the realm of probability the odds are a flat zero, that's 0.0, of proving the existence of God. All knowledge of the Biblical God comes by way of revelation. So say the scriptures.

Conversely, in the realm of the dimensional universe, all is cause and effect: until you get to the macro, beyond our observable boundaries or into the quantum realm where you have, say, matter/energy existing in two or more places at the same time, multi dimensions and an incomplete menagerie of theoretical thingies. We attempt to reach beyond our senses with mathematics which tend to serve us well in the observable universe. Can't say that they serve us well in the theoretical universe.

If only all you can see is all you believe then atheism DOES make sense. Apollo 8 astronaut recited Genesis 1:1 from inter-lunar space. A Russian cosmonaut declared that he had ventured into "heaven" and could see no god. Both were right. It just depends on your point of view.

Back to earth now.   A nurse or any other person who subscribes to a system which extols the virtues of benefiting mankind and doing good with a selfless interest is a good thing and what ever motivates them to do such deserves honor and not contempt and sneering. No one can force you to believe what you don't want to believe so have a little charity and good will in your heart and be thankful for whatever motivates the good deed doer.
