Here you go. There are infinite mutually exclusive possibilities for god or gods, such as the Christian god. For any one of these to be true all the others would have to be false. For one specific one of these to be true would be infinitely unlikely. Mathematically .0000X1 where X is infinite 0’s is the same as 0. So if anyone asks me if their God exists I can answer, “No. There is zero chance your god exists.”
