Actually the supposed dispute with science is just, in many ways, a smoke screen. When they are talking about a creator god, who existed before or outside the universe, they are talking about something beyond science, since science does not claim, (Science being basically, just honesty organized.) to know anything about the, possibly, none existent, realms beyond the universe, or have anything to do with them.

The trick therefore, that they are using, is the old magicians ploy of misdirection. By pretending that science has something to say about that realm beyond the universe, and pretending to disagree with it. They redirect the gaze of the gullible, away from the completely unsupported assumptions they are making about things beyond the known universe, into the phony dispute with science, about big bangs etc. Thereby getting all their wild, evidence free assumptions overlooked.
