I wouldn't normally redress a single religion, but other religions have not tenaciously battled to implant their faiths into a discipline that requires the exact opposite of faith. Scientific conclusions are based on research and evidence. Experiments are administered and results are published. If the outcomes of experiment after experiment support a theory, stacking evidence upon evidence in favor of the theory, then and only then is the theory eligible to be taught in science class. Allowing faith in science class sets precedent for kids to supplant mysticism and superstition for rational thought and evidence, two vital ingredients in the solid foundation of all scientific disciplines. Science teachers do not just fill in blanks with whatever religion conveniently gives explanations based on assumptions and a complete absence of research. What happens when two religions give equally logical explanations of the same event? What makes us choose one over the other? Faith?
