A god may exist. "God" - Jehovah-Jesus - does not.
Your god is logically impossible. There may yet be a god or gods, but it isn't yours. Here is the argument:And your proof of this is what?
There are no perfect gods with perfect love, perfect knowledge and perfect power watching over us. That pretty much rules your god out right there.
So does the creation myth, in the light of modern science. A real god would have gotten the actual history of the universe and of life correct.
What else? Oh yeah - nothing exists outside of time. Nothing thinks outside of time. And nothing acts outside of time. All of those verbs require time. They all have before and after states - a was and an is.
There's more, but that's enough for you to ignore for now.
