And if you accept time as a progression of events too...
And God's actions must've had a beginning. God must be part of time since he's acting in a progression of actions (events). God could not have acted in any kind of "Now" before "Now" existed. Time must exist before causes can exist and events can exist.
Time did not exist before God created the universe. Even science acknowledges that time began with the big bang. Yes, in the material world, time must exist before causes, but God is eternal and therefore not subject to laws of the universe.
Don't waste my time. The Universe is God.
The universe is not God. There are those who believe nature is God, I suppose that is what you propose. If you make something, do you become your creation? Do you cease to exist when you've made it? God created the universe, but He's independent of his creation.
