Why do evolutionists say evolution IN HUMANS has been PROVEN as a fact (please read question before answering)?

That's the ONLY logical explanation! Otherwise the other way is that Eve must had with her only living son! And how would you explain the many different races. It's nice to believe in Adam & Eve, I was brought up in a very Roman Catholic School. But if you dared ask about Moses being Jewish and the Ten Commandments that God gave to Moses, well you would have thought I hung Jesus myself!
