"A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven. Basically, if evidence accumulates to support a hypothesis, then the hypothesis can become accepted as a good explanation of a phenomenon. One definition of a theory is to say it's an accepted hypothesis."
Edit: Not sure where the confusion is, abiogenesis is a hypothesis, it has yet to be verified or disproven; the evolutionary theory is a theory, currently it is verified and not disproven.
