Just to throw this in about the logical impossibility of free will/omniscience, so we're clear.
I don't know what I'm going to have for breakfast on March 18th, 2015. God does. He might not care much, but he knows - he knows everything. So, God knows I'll have Weetabix & toast.
Now then - whose choice will it actually be when I do indeed eat Weetabix & toast? Mine? It might feel like it's mine - but actually, simply because God already knows about it, then my breakfast menu is preordained and I have absolutely no choice in the matter. If I really had a choice, God couldn't know what I was going to have....my "freedom" to choose is therefore non-existent. If I surprise God and have Cornflakes instead, then I disprove his omniscience.
So, it's not possible. There's nothing "free" about our will if our choices are preordained in any way - and they HAVE to be if God is omniscient.
Now, your response was "God is outside of space and time". And, I take from that, that logic doesn't apply to God in the same way it does to us? This is a cop out of epic proportions - but, OK, let's follow it through.
God is not subject to logic. You can abandon all logic when you talk about God and his properties.
So, on this basis, when talking about whether God exists, we have three choices:
- God exists
- God doesn't exist
- God exists and doesn't exist at the same time
Without logic - all three of these choices have equal weight.
In two out of these three choices, God does not exist. By following your logic, we show that God is more likely not to exist than to exist.
Deploying Occam's Razar, "The simplest explanation tending to be correct" - we must rationally conclude that God does not exist, since that is more likely.
So, you see - writing the argument off as "God is outside of space and time" does not help. It makes things worse.
