Time and how it relates to God?

I've been trying to determine if God exists and I've been thinking if he was created by another more superior God? No God created himself. time can be stopped or slowed down maybe even sped up. Time is all an illusion, If time is an illusion everything that is happening will happen and already has happened to. I can be dead before I am born because it has all already happened because there is no actual time this is the only way to make anything out of nothing as we see in the big bang. Are we actually who we think we are? Is what your doing right now something you've never done before or has it already happened?
