Children learn better than adults. The sheer amount of mythology in existence would be quite difficult to absorb for an adult. This is the same reason we teach children math, literature, and science.
If your child is learning stories from the bible in school, and being taught it as fact rather than as mythology, then that's illegal and you should bring it up with the school. More than likely, they are not doing this. In fact, schools aren't allowed to be teaching stories from the bible at all, and teachers are usually liberal, so it's far more likely that you are making shit up to fit your point.
Perhaps it's a parent's job to teach their kids to tell the difference between facts and fables. Are you upset when your daughter comes home wondering what ever happened to babe the blue ox, or talking about George Washington cutting down a cherry tree? Or the fact that there was most likely never a real boy that cried wolf and then got eaten when the townspeople had enough of his shit? If your daughter went to school and said that her father told her that the story of the great flood didn't actually happen, and was just a story to try to teach a lesson, she would not get in trouble, and the teacher would most likely agree with her. That is unless, of course, you are sending your child to Catholic school, in which case you have no room to complain as that was your choice.
