should creationism be taught in schools?

Creationism cannot be taught as a part of secondary school or college science curriculum, simply because it is not science. All science, necessarily, is based on the scientific method. The latter means that every single word that a science teacher utters is based on people's observations of the natural world, which were followed by questions, hypotheses, predictions, and tests. Obviously, one cannot physically observe God, and one cannot, therefore, study God or God's work through the use of the conventional scientific method. That does not, of course, mean, that a person cannot believe in God or in that God is the Creator of everything; yet, if one has this belief, no scientific exploration of it is possible (or called for). --Richard
