>>>>Can you prove God doesn't exist?
Immaterial, the absence of proof is not proof itself.
If you cannot disprove the existence of God, you must allow the possibility that He exists.
Ultimately, what you will come up with is not proof--verifiable facts--but rather a level of probability. Everyone comes into the debate with their own set of experiences (with emotions) and type of education that will determine how they evaluate the evidence. What is sufficient evidence to one person will be nonsense to another. It has always been this way. If the existence of God could be proven to everyone, there would be no debate.
Maybe a proper challenge would be: "Convince me that God exists."
