Religious people think "theory" in science means a wild guess.  It's a given for the sort of ignorance they are used to.  In fact, in science, a 'theory' is defined differently.  It means it's a "working theory".  EG: gravity is a working theory.  The speed of light is a working theory.  Momentum in physics is a working theory.
The close-minded, think theory in science means a wild guess. In science, a 'theory' is formulated fact that can be improved on. That's the basics of it.
