I think I agree very strongly with Yaro, on all points.
Thinking that creationism can be taught in science classes as an "alternative view" or "alternative theory" simply destroys the purpose of teaching science. Creationism, by definition, is outside of the scope of science because it deals with supernatural. I am a Christian and I very sincerely believe that God is the Creator of all, but I do not know it because I learned it in science class - I simply believe it, in a way like I believe that I exist and the world exists. It's a basic truth for a believer, it does not need to be taught "scientifically" and it does not mesh or mix with the empirical method of modern science.
I grew up in the former Soviet Union and I know from experience of my parents' generation, what tragedies can follow when people who are, allegedly, scientists, stop following the commonly accepted rules of the scientific method and sacrifice science for ideology. In the USSR of the 1940's - 1950's genetics was officially declared wrong, because the Communist party line was, genes do not exist, everything is "nurture" (implying that proper indoctrination by the Communist authorities can change everything, and these weird "genes" that resist the direct influence of the environment must be simply put out of the way). When I think about teaching the scientific theories such as the TOE and the anti-scientific ideologies like creationism as simply two alternative "views," I sometimes make a mental comparison with teaching genetics and the 1940's Soviet-style "advanced biology of Michurin-Lysenko-Marx-Engels-Lenin-Stalin" as two "alternative views." Why, let students decide what they "believe" in, right?
