Greeney, you asked for what logical proof of God's existence I would accept.
I'm trying to explain why that question doesn't really make sense. Logic isn't like observation, or direct experience. Logical proofs are proofs in the form proposed in this thread - the ontological argument - so you seem to want me to compose my own logical proof of God.
But I'm an atheist, and my position is that no such proof exists, so your question makes no sense to me.
Now, what I think you're trying to ask me is "what would I consider proof of God's existence", which is a completely different question to the one you asked. The answer to that question would be "I'm not sure".
You might think this is a copout, but most people do not know exactly what it would take to make them believe something to be true. I am sure, however, that if there is a God and he wants me to be a believer, he does know what proof would convince me, and if he sees fit, he will provide it.
I would certainly be swayed towards belief if I witnessed a true miracle, though. My whole worldview would change drastically if I directly experienced something I considered supernatural, or paranormal, and I was not under the influence and of sound mind. A direct experience with God would also probably sway me, but it would have to be very clear it was God and not a figment of my imagination. I would also be swayed by any valid logical proof of God's existence, but knowing what I do of logic, I am pretty sure such a thing cannot exist.
I hope this helps.
