For another reductio ad absurdum argument*:

If we can pray to God and convince Him to change His plans for the better, are we not offering Him a more holy way to govern the universe? Are we not showing Him a path that He, in ignorance, overlooked? Is not the creature more wise than the Creator?

*as such, this shouldn't be used as your first line of defense. This should be held back for a time when the person is particularly arrogant and rude in his/her argumentation. Hopefully, you'll "nicely" bring them down a few notches with such questions.
