A theory is a belief that explains lots of observations, unifies prediction rules, and is connected to other beliefs, all in an explicitly testable (dis-proveable-false) way. A good test of the coherence of theories in general is what they have measurably produced. Creationism had all of history until the 1860s and didn't do squat. I'm not holding my breath for creationist biomedical companies.
