The whole “demon” thing is ridiculous and makes you sound paranoid. I never understood the “need” for demons. Humans don’t need a reason to screw up. Demons are an excuse for being weak and lazy.

Either it postulated man as god, or aliens with powers far beyond man's (God substitute).
Much of the point of science fiction is to create imaginary realities where there is no God, thus conditioning people into the idea, away from the traditional religious thought.
There is hardly any science fiction in which Christianity plays a substantial part, except to be ridiculed.
Rule out nothing.
