A is an important question, but a completely different subject altogether.
B would follow from A being true, and how the question is answered depends on the nature of the creator and his relationship with his creation.
Some might the Deist route and say that the watchmaker wound the watch and walked away. I argue for a creator that cares deeply about human flourishing on an individual, interpersonal, and societal level, and would thus want to regulate something that is immensely consequential for all of these spheres.
There's an idolatry angle as well, but I don't wanna branch this thread too much.
A. Does a creator exist?
B. If so, would it care about where we put our sexual organs?
I see those often conflated: "There can't be something from nothing, so the universe must have been created, so the Bible must be true!" -- Eh. WAT?
