Since the debate about origins cannot be solved with certainty, you may have a point about leaving that discussion out of science in primary schools and take it up in philosophy classes. Because when all is said and done it is a philosophical question. Both EV and ID start with a philosophical premise. I think that delving into Quantum Physics brings one to the possibility that matter is not as real as we suppose.
"Both EV and ID start with a philosophical premise"
Bingo. And in high school level science you need not even go there. Simply fast forward to the scientific method, and turn out the pre-engineering students. We will all be better off. No loss of religious freedom. More engineers means fewer lawyers, etc.....
