If a student asks, "What's 2 plus 2?" the teacher can give a factual, definitive answer; the answer is known and provable.
If a student asks, "Where did the Universe come from?" the teacher should say, "We don't know. Ask your parents what their beliefs are. My beliefs don't matter to you. The school board's beliefs don't matter to you. The Supreme Court's beliefs don't matter to you. Because nobody can say for sure and all answers are based on faith of one kind or another."
I'd like the "Ask your parents" reply mandated in other matters as well; such as the proper installation of a condom.
Why would you want the teacher to lie to the students? And to grossly misrepresent the evidence? And to mislead the students about the strengths of the scientific method and how it results in reliable knowledge that is far beyond "just faith"?
Oh, right -- because you don't have a clue about any of these things, and planning to pass your misconceptions along to the next generation.
I've got a better idea. Let's leave education to those who actually have knowledge of the subject, shall we?
