A theory isn’t a notion or a tale or an idea or a concept or a guess or a rationale for a religion’s myths. You can’t have a real theory that isn’t supported by evidence—that’s why rational people, not just atheists, have screaming fits when you present your “theories.” In conversation, “theory” can mean ‘a wild-assed guess’ or ‘a notion about how things work,’ which scientists would call a hypothesis; but a theory in the scientific sense means ‘an explanation that can be tested, that has predictive power, and whose predictions have been tested and shown to be correct.’
If the predictions are wrong, the theory must be either discarded or, more likely, modified to explain the actual results. A theory is based on reality. Scriptures of any religion are not evidence of anything except the ability of humans to create and believe their own fiction.
