I have noticed this as well. But don't forget the evolutionist chrstians who subject Genesis 1-11 to scientific critique but who get on their knees and become "as little children" with the miracles and alleged supernatural phenomena of "the new testament."
So are you claiming that the scientific DNA evidence of the American Indian/Asian connection, instead of the Mormon claimed Jewish heredity is a miracle?
We actually have zero evidence that the Virgin Birth did not occur, whereas we have lots of evidence, IMO, that evolution did occur. The only reason we can offer for disbelief in the Virgin Birth of Christ is that we've never seen such a birth. But that I've never seen a black swan or a little green man is not proof they don't exist.
IOW, the general tenor of past history can be determined from the evidence. Occasional miraculous interventions, which to my mind are just God making an exception to the rules, cannot be disproven by scientific means. Or, of course, proven using the same methods.
