Well, faith and fossil records and variations of species. EVOLUTION DOES NOT EXPLAIN GOD! It explains how A got to B- but not how A got there.
No. It's just a theory. All of it is a guess. None of the fossils of "early man" have any human DNA. They're still animals.
Not only that, but in one huge evolutionary jump, the entire back bone and skull change from that of a monkey to that of a bear. No one even discusses that part. It doesn't fit the "theory."
