Is there anything that suggests that God is an impossibility?
Nope. But keep in mind that to give validity to the god of the bible/quran for the sake of not being able to show that this god is an impossibility is to give the same credence to all gods that man has or does deem real/true. In the "evidence" department, IMO, they're all on equal footing.
Is there anything in science that makes it clear that God can not exist and could not have had anything to do with the universe?
Nope because science does not concern itself with *claims* of the supernatural. Supernatural claims are probably best left in the area of philosophy and theology.
