It should be simple.
Science is taught in science classes and religion is taught in religious studies or whatever they are calling it nowadays.
They both get taught in their respective classes.
Science should be able to teach that Evolutionary Theory is an advancing subject that does not yet have all of the answers without God being brought into it. Or would Creationists like the boot to be put on the other foot and have science interfering with religious studies classes?
Science would have a lot to say about the legitimacy of the Bible, particularly the New Testament. Christianity is a religion based on a person who appears to have escaped all documentation under the obsessive Romans and for whom there is no hard evidence that he ever really existed.
And I would just love to get in there and explain to all school children about brainwashing, particularly by their religious parents.
