Science is an open system based on skeptical inquiry, and its ultimate appeal is to experimental evidence. Creationism is a closed system based on belief, and its ultimate appeal is to the Bible. This is evidenced by the demand that their members sign a statement affirming that they take the Bible as literally true. It is difficult to imagine evolutionists signing a comparable statement that they will never deviate from the literal text of Charles Darwin's Origin of Species. Fanatical dogmatism is just not acceptable in science.
Scientists use inductive reasoning to formulate general laws from specific observations.
Creationists base their beliefs on Scripture and use deductive logic to try to explain how the universe must act to conform with Scripture. When scientific findings conflict with the creationist's interpretation of the Bible, the creationists ignore the facts and distort the theories. In other words, creationists have trained themselves to shun the unfettered inquiry and hard-nosed skepticism that are the hallmarks of science. Creationism also differs from science because it is not explainable by reference to natural law. Creationists counter that scientific tests are themselves wrong, which is absurd, considering the success that science has had in harnessing nature.
