Sociologist Jon P. Alston offers a unique and clear analysis of the weaknesses of scientific creationism and intelligent design by identifying what creationists say when they reject evidence for evolution. He demonstrates how scientific creationists accept non-scientific statements that contradict established scientific knowledge. Acceptance of anti-evolutionary knowledge also demands acceptance of a literal six-day creation and other statements contradicting scientific findings.
Few persons have read so closely the writings of scientific creationists to illustrate how anti-scientific anti-evolutionists become when they criticize the fact of evolution. Creationists are forced to develop "just-so" stories to defend their literal interpretations of Biblical scripture. Alston finds creationists cannot defend their religious beliefs using established scientific methodologies and principles.
