Parents can teach their kids what the heck they like.
Schools should teach science in science lessons- the clue is in the name. I gather the US does not have Religious Education lessons in schools – this is a pity. RE isn’t about teaching kids what to believe, its where they learn about many belief systems. If you want to discuss competing creation myths, you need RE. This is perfectly compatible with the US being a secular state if the teaching is unbiased.
