@Muarck,
The kiddies can believe whatever they want. This discussion has been focused principally upon what should be taught in SCIENCE curricula, Specifically biology. They are allowed no "space" in the curriculum outlines. We require a certain proficiency in the subject , demonstrated by attainment of certain grade levels in tests. Their "belief" system has nothing to do with anything.
If we teach geography and the kids want to believe the earth is flat, so much the pity. Hiwever, geography will not waste any time on bringing flat earth garbage into the course syllabus. What you and several others wish , is to burden the existing curriculum with some of the past thinking. We already do acknowledge that the sciences have developed from sequences of ideas that led to the modern syntheses , as well as several dead ends of myth based learning that , as soon as evidence xountered, was sent to the ash b in .
Teaching the historic perspective is entirely different than teaching as if the concepts of , say, phlogiston, flat earth, or Creation were true becasue that would be, scientifically, a lie. None of the above have a smot of evidence in support and that just wont due when we are trying to teach fact , testability and predictability.
Whatever the kids do once they leave the classrooms is not governed by any thought police. They are free to believe in any myth they wish. From the news, its obvious that some kiddies do. Witness the appearance of "Vampire cults" where kids get their canid teeth ground to points and get long pointy dental appliances so they look like Bela Lugosi. Then they go around sucking each others blood in the wacked out belief that they are , somehow, sharing in the bodily strength of others.
However, no math proofs exist yet.
