Its unfortunate that you feel that way. It seems you want to replace the facts (physically available data points) used by science to explain our existence with the 'facts' of the Bible. How is your desire to insert your beliefs any more 'free' than the restriction of science to science class, math to math class and health to health classes? Is your desire more or less totalitarian in nature than what secular society requests?
What is taught in science class is necessarily restricted to science, to do otherwise would quickly open the door to such things as pyramid power.
