A repeatedly tested hypothesis becomes a fact when its continued verification shows that to not consider it so would border on the ridiculous. For those people who want to see and understand the world in terms of absolute truth the scientific characterization of the word fact can be troublesome. He or she is employing a technical meaning not the common dictionary meaning of the word. Hence, scientists often hold that evolution is a fact as evolution is a verified scientific explanation of the origin of human life. This does not make evolution nor the theory of evolution absolute truth.
Human evolution is simply the scientific explanation for the origin of human life.
The supernatural phenomena of human creation is beyond the limits of the objective reality assumed in science. Moreover, there are other limits in science as well. Just as absolute certainty is not possible in scientific explanation neither can science determine what is right and wrong, moral and immoral, nor beautiful and ugly. Science cannot determine whether or not God exists nor explain God's nature nor the purpose of human life. Science affords prediction but not prophecy nor spiritual understanding.
