I have a number of proofs that God does not exist. One original one is the following:
Einstein's full equation is E=mc^2*gamma. Combine this with P = E/t to get P = mc^2*gamma/t.
Simplify to power = mass x stuff
Claim: God is immaterial.
Translation: God's mass is zero.
Plug in: power = zero x stuff = zero.
Thus, God has zero power, which means He doesn't exist.
There are contradictions as to how much God can know being omniscient. It has been proven mathematically that any system for ascertaining true statements will have statements incapable of being ascertained. This barrier applies to any system God has as well. Thus, God cannot be omniscient.
There are other proofs against God as well. But, if it is proven in even one way, that is sufficient to do the task. God is a myth. This is why prayers don't get answered, for example.
I am sorry if I have shown your faith to be false. But, for me, I would rather know the truth and act in a better way for my future than do things that are not true ultimately wasting my time since we only get one life.
