Since the Scientific Method pertains to what is 1) Testable, 2) Observable , and 3) Repeatable, no past event can be dealt with scientifically. Even the whole idea of "pre-historic" is a new concept and a newer word. There is nothing before recorded history, for the very beginning of history has been recorded. I think that there is no way to misunderstand the clear teaching of Scripture when it states that man was made on day 6, so I must be classified as a "young earth creationist." I think that no compromise is made by choosing this position, because I would rather that God be true and every man a liar. Thanks for the @williambanks link, I have seen some of his articles, but not that one.
