How about teaching both viewpoints? Or teaching evolution and at least mentioning the ideas of creationism?
We do not teach the Axis side of World War II. We do not teach the alternatives to the reality of the near-spherical earth not the center of the universe. We do not teach that astrology has value. We do not teach Afrocentrism. We do not teach sex education from the standpoint of sexual criminals. We do not teach about unicorns, leprechauns, griffons, and fire-breathing dragons as genuine living things.
Children need not be taught nonsense.
