Evidence against evolution
Why do scientists reject such arguments? Creationists suggest it's prejudice. Keep in mind, however, that scientists are trained to question assumptions; whereas creationists are taught to protect core assumptions.
Without scientific research experience, the apologetic nature of "arguments against evolution" may be obscure. These arguments don't address or (experimentally) test specific hypotheses. Antievolution "arguments" are rationalizing by apologists. Apologists begin with conclusions, then collect arguments favoring the conclusion and casting doubt on alternatives. Apologetics are scientifically unacceptable. Scientists on the other hand make predictions (not retrodictions) which distinguish among models. They test these predictions. The scientific community accepts theories which survive rigorous testing.
The American scientific community has accepted the "theory of evolution" since about 1873 (death of Louis Agassiz - the last influential opponent of evolution). Evidence is, in fact, rapidly accumulating for evolution (not against it). Only a superior model can overturn evolution, and none is on the horizon. Although there's still much that evolution can't explain, there's no serious debate about acceptability of evolution within the scientific community.
What is creationism?
Creationism is at one extreme simply admission that ultimate origins are beyond comprehension. At the other extreme creationism is a form (several forms) of organized ignorance. It's goal is to circumvent science by promoting apologetic alternatives. Typically apologists make arguments but avoid testing hypotheses. Creationists seek to obscure science and to solicit testimony from scientists chosen for religious beliefs rather than scientific credentials. Creationism (including intelligent design) is marketed to religious groups and not to the scientific community. It promotes fundamentalist religious views and obscures science. For a concrete example Vision University offers a Masters Degree program in creationism which requires no science at all. Most Bible colleges teach little or no basic science.
