Calling evolution a fact is like calling the law/theory of gravity a fact.
Yes our theories do a good job of explaining what we observe in the physical world. So it is a good workable theory. HOWEVER if you really get to questioning an honest physicist they will tell you they have no idea actually what gravity is or how it works. So yes the theory of gravity is good science but you can't call it a fact.
Sometimes religious minded people become very dogmatic and close minded. However those that choose to follow science are prone to the same thing. A good scientist should stay skeptical and curious about EVERYTHING. The moment you think you have every thing figured out is also the moment when you actually know the least.
Stay curious my friends!
