Evolution was an hypothesis. Over the years it has been supported and modified and generally accepted as a theory except by those that have been taught to believe otherwise based only on a 'faith'.
And the evidence against it is generally discarded, even by proponents. I again use the "it used its wings as a net to trap bugs" explanation of how birds first flew.
Once it was disproven (mostly by an aerospace engineer) the proponents said "Oh, well, the theory served its purpose."
