Yes, but just because we accept it as fact, doesn't mean that it can be proven to be true. It just hasn't been proven untrue yet.
I know that evolution is how it happened, you know it is how it happened, but this knowledge is drawn from a huge pool of different data that all suggest the same thing. If we only had one piece of this data, one could still create a theory of evolution from it.
Don't forget that up until X point in time, there was a whole lot of observations proving that Jesus was the son of god and could do all sorts of magical things.
Someday we may discover a crashed U.F.O. or something, and it turns out all wombats in the world came from Mars to Earth on it.
On that note, that is the best way faith can contribute to science, the same way race, culture, and upbringing can contribute to science; they provide a diverse population of scientists not just to try to prove what they "know" is right, like evolution, but to challenge it.
