Your fallacy is thinking Time is linear. Time is non-linear. It does not exist at the meta-physical level. Time is a *dimension* of mind. After you die will finally grok these concepts, so don't worry about it if you don't "get it" while human - most people don't.
But is Time wibbly-wobbly?
So why does god get a free pass to come from nothing?
He doesn't. If he exists, it's somewhere outside this universe- somewhere we can't see, since the light from anywhere outside the universe will probably never reach us (something about being inside a giant bubble or whatever). To be honest, I pulled that theory straight out of my ass, so I'm not going to defend it at all.
If you push the "extra ice" button on the soft drink vending machine, you won't get any ice. If you push the "no ice" button, you'll get ice, but no cup.
