Theory: A belief that can guide behavior.
A theory by definition is a model or framework for organizing the factual evidence. A hypothesis is a provisional idea that remains unverified. You seem to have the two confused.
Evolution is a theory (i.e., a set of axioms, principles, models, and definitions extrapolated from the evidence).
Creation is a hypothesis (i.e., wild-ass guess).
The "theory" that George W. Bush was born from Barbara Bush is a belief system no different from the theory that he was born from a humpbacked whale.
Well, there's a little bit of difference: one is TRUE and the other is FALSE, and one is supported by FACTS and other science, the other is NOT. Aside from that TINY difference, both are equally valid theories </sarcasm>
