. At that point, that is where faith comes in. To my knowledge there is no way to absolutely, without a doubt prove that God does not exist so the question comes down to “What are you putting your faith in?” I don’t think evidence alone can convince someone 100% one way or the other so that is where faith comes in.
Depends on which god. The Christian god? Absolutely.
There's several ways to do that.
1) God is, according to scripture, all-knowing.
2)God is also, according to scripture, all-powerful.
3) Either the future hasn't been determined yet, and thus can't be known, or it has been determined, and thus cannot be changed.
4) God cannot exist with the two aforementioned attributes in a universe in which time is determinative.
Or
1) God said Tyre will never be rebuilt. (Ezekiel 26:1-14)
2) Tyre was rebuilt, and exists today.
3) God either was wrong, or he lied.
4) Scripture claims god is perfect.
5) Perfect beings cannot be wrong.
6)God must have lied.
7)God is, according to scripture, without sin.
8)Lying and being without sin are mutually exclusive.
9)These two traits cannot exist in one being.
10)God cannot exist.
Or we could just phrase it even more simply.
"God is all merciful" and "God is perfectly just."
You cannot have perfect mercy and perfect justice at the same time, because mercy is a suspension of justice.
There, the Christian god disproved as being logically impossible. Did you have another god in mind?
