God has yet to be disproved by science; it's unlikely that will ever happen, actually, no matter the fact of God's existence.

There's also no general framework from science that makes God incompatible with known laws.

So God, in the context of a sci fi book, belongs to the class of things that have yet to be discovered but which are still consistent as possible discoveries.

Even aside from that, you can have concessions made to the willing suspension of disbelief. There are limited concessions made in all but the strictest of science fiction for the sake of making a compelling story.

I can understand if you have such a strong distaste for those kinds of ideas that it ruins a story for you, but that's a matter of taste, not any necessary quality of the genre at large.

"God" will never be disproved by science since there's no real definition of God. Between the thousands of conceptions of God and the eternally moving goalposts (under which god will eventually be (or already is) defined as 'something impossible to test by science'), it's completely meaningless in an empirical pov.
