You realize that one of the definitions for a "myth" is a story that is unverifiable, correct? Explain to me how one can reproduce evolution, empirically, such that it is fact, again?
We can't kill Nicole Simpson all over again. But we can look at the clues and figure out that OJ did it. That's how it is with any historical science. Life on Earth developed over time, and all species are related. Those are facts.
