The Premises of Scientific Creationism
Answers to creationist arguments have been provided in the Evolutionary Theory FAQ and in numerous articles and books, so they will not be discussed here. Instead, this section focuses on the philosophical premises behind the scientific creationist movement.
The main premises of scientific creationism are, in many ways, in opposition to the premises of actual science. First, scientific creationists see no need to prove their theories, and firmly believe that healthy scientific disagreements between evolutionary theorists are evidence that the whole idea is false. Second, creationists - whether they admit it or not - are fundamentally basing their arguments not on evidence derived from real-world observation, but rather from religious dogma misapplied and misinterpreted. Third, creationists think that evolution, too, is religion, is based on faith, and therefore is on an equal footing with creationism. Finally, creationists misattribute social evils to the rise of evolutionary theory, and cite this as proof against evolution.
The Burden of Proof
Creationist assertions aside, there is currently an overwhelming amount of evidence in support of evolution and of associated facts in geology and astronomy. Fossil evidence, molecular evidence, radioactive dating, etc. all converge on one common point: the earth is old (about 4.5 billion years) and life has evolved. Creationists, however, do not realize that the convergence of this amount of evidence is tantamount to certainty. They commonly take a smaller puzzle, a question or discussion of how a particular thing might have evolved, and claim the discussion as proof that evolutionary theory is "in crisis" (For example, the debate over punctuated equilibrium is commonly misrepresented in creationist literature.)
Creationists often think that disproof of an evolutionary idea - or even just disagreement among the ranks of evolutionists - automatically supports creationism. As a result, they spend a great deal of time picking at minor details of evolutionary theory, and very little time proving their own case (which is fundamentally unprovable). By using this tactic, they not only take controversy within evolution out of context and out of proportion, but also misrepresent the evidence for their own theory (which, when examined closely, doesn't amount to much.)
In addition, it must be emphasized that the burden of proof is on the creationists and their claims that contradict much of established science. It is not enough to say "Prove evolution" and, when not convinced by the proof, declare the theory false. In addition, though some true arguments have been maligned by the scientific community (i.e., plate tectonics), merely being in opposition to established theory does not guarantee - or even imply - correctness.
Scientific Creationism Isn't Science
Though many scientific creationists deny their religious affiliations, creationism is fundamentally a religious theory, not a scientific one. As mentioned above, it is not based on real evidence. In reality, creationism appeals not to the scientifically-minded, but rather to those seeking to protect their religious beliefs from what they see as the threat of Darwinism. If scientific creationism were a science, it would not take all the "evidence" it offers from a holy book written thousands of years ago, before the advent of anything approaching modern science.
Moreover, scientific creationism's fundamental assumption - that the Bible is literally true - is the exact polar opposite of true science, which is always open to disproof or revision. For those who argue that creationism is not religious, consider this statement from the Institute for Creation Research: "The Bible . . . is the divinely-inspired revelation of the Creator to man. Its unique, plenary, verbal inspiration guarantees that these writings, as originally and miraculously given, are infallible and completely authoritative on all matters with which they deal, free from error of any sort, scientific and historical as well as moral and theological" (ICR Tenets of Creationism).
It is for this reason that scientific creationism does not belong in the educational systems. Scientific creationism is religion, not science, and religion cannot be taught in public schools as literal truth. It could be appropriate to discuss the creationist movement and tenets in history or sociology classes, but creationism does not meet the criteria required for inclusion in scientific curricula.
