Science and evolutionism are two different things indeed, the latter defined as the ideological belief that things will always evolve to the better. Evolution theory, in contrast, is a part of science, where predicates like "better" have no place at all. The popular phrase "survival of the fittest" is no longer accepted as science.

If a scientific theory is valid, it will be so (sc. to the same degree) for the past and future, and for other countries etc. Therefore it is perfectly possible to explore the past from present-day data scientifically. Of course the accuracy is not perfect, but well worth the while for many curious people. Not to speak of those who are after the fossil oil etc. - if they all were Bible literalists, cars would have run dry long ago (- not the worst aspect, on second thought).

Pete has told us where he got his "wisdom" from; trying to convince him is completely pointless. There are other readers who are really interested; let us address them and try to make a good impression.
