Why do religious people misuse the words theory and belief?
It’s not religious, it’s uneducated and for the same reason you just misused the definition of a scientific theory. We’ll use wikipedia just because it’s easier to quote one source, not the numerous others with the same ideas and statements: A theory, in the scientific sense of the word, is an analytic structure designed to explain a set of empirical observations. A scientific theory does two things: 1. it identifies this set of distinct observations as a class of phenomena, and 2. makes assertions about the underlying reality that brings about or affects this class. In the scientific or empirical tradition, the term “theory” is reserved for ideas which meet baseline requirements about the kinds of empirical observations made, the methods of classification used, and the consistency of the theory in its application among members of the class to which it pertains. Gravity is a theory. If you can prove what gravity is…. well, you probably would have been smart enough to understand there
