If one takes it that the Resurrection actually took place, then it is as much a fact as that a peach tree bears fruit.
Since I'm a Roman Catholic, I obviously agree. But the point is that such truths are not part of nor provable by science--they are outside the realm of science. You can prove the existence of God by reason (as the Catholic church teaches), but NOT by means of any known scientific test or method. If you come up with one, I guarantee you'll win the Nobel.
