Don't say either: 1. "god is outside our universe". Then, he wouldnt be able to do anything in our universe. Obviously. He'd have to go in it, if only temporarily, to pull any strings.
Or, 2. "god built these rules, so he's outside it anyway". That is just a foolish cop-out low-intellects take, not realizing the foolishness of it, to explain the supernatural. It makes no sense at all.
I write a computer program that emulates a world. I run that program on my computer. The emulated world runs in accordance with some laws that relate to force and other concepts within that emulated universe. There is even some randomness injected into the emulated universe. It turns out that life evolves in the emulated universe.
As the programmer and operator of the computer, I am god with respect to that universe. However, I am not god in our own universe.
With respect to the emulated universe, I can change things by modifying data in the current state database. Or I can also modify a few lines of code. I am not in any way bound by the laws in that emulated universe, because I can get around them by changing what is stored in the current state database.
Now what was that you said about impossibility?
Let's end the political smears
