Such a question seem to be making the assumption that only some powerful intelligence could 'make' things follow physical laws. This should, if you are rational, cause you to wonder what 'made' this powerful intelligence... then what 'made' the maker... what 'made' the 'maker' of of the 'maker' of that powerful intelligence.. etc. etc.
For physicists, things are always observed to follow physical laws. That is sufficient.
I've been in enough discussions where this point always arrives and I cannot explain it, I can only observe it and accept my observations as accurate. That a person states that visible, sensory, predictable physicality just happening to exist is an absurd claim. But an alleged magical creature infinitely more complex and intelligent similarly just happening to exist is not. For the latter we need no explanation, accounting, or proof, but for the former, we do not accept any of it as real without the latter. It's simply astounding to experience, a gift.
This will always be the most fascinating, revealing and fulfilling observation I shall ever make of the human species.
