Evolution is on the other hand a scientific fact. Let me give you a definition of The Theory of Evolution.
In science, a theory is not a guess, not a hunch. It's a well-substantiated, well-supported, well-documented explanation for our observations.2 It ties together all the facts about something, providing an explanation that fits all the observations and can be used to make predictions. In science, theory is the ultimate goal, the explanation. It's as close to proven as anything in science can be.
Evolution (genetic change over generations)3 happens, just like gravity does. The Theory of Evolution by Natural Selection is our best explanation for the fact of evolution. It has been tested and scrutinized for over 150 years, and is supported by all the relevant observations.
