The one thread running through "scientific" creationism is a fixation on particular arguments or "proofs" to the exclusion of all else.
Good scientific judgment is the art of weighing all these variables and properly evaluating the big picture.Since careful inspection shows no signs of such a flood, the earth can't be older than a few weeks! We do need to know something about the system under study. No one familiar with tides would assume that the rate of water going out is constant over weeks of time!Just as obvious, at least to the experts, our sun could not have been continuously shrinking over millions of years as described by some creationists.Contrary data and isolated arguments are important in that they carry the potential for bringing down a theory or hypothesis.That grand potential is seldom realized in the light of further investigation.When great scientific ideas do fall, on rare occasions, they do so of many grievous wounds followed by the rethinking of the total picture.The idea, literally worshiped in creationist circles, that you can disprove a theory by whipping out some cute, isolated "proof" that settles everything at once and for all, is not scientific.Furthermore, isolated data, even if correct, are often misleading.Consequently, scientists must evaluate the total picture and avoid being fixated on specific points. This magic bullet mentality, the tendency to rely on a single, isolated argument to win all the chips, has gotten creationists into more trouble than possibly anything else.Unfortunately, Mother Nature does not give little, gold ribbons to certify the accuracy of our proofs!
