I don't think that "religion declined and then science progressed" that brought Europe out of the Dark Ages. I think rather that because science was progresssing, that brought about the decline of religion.

I think the USA tends to dig its heels in about religion because we're so far removed from Europe. We don't have the scars from all their religious wars and haven't learned our lesson. In addition, since we're a baby country, we haven't had those kinds of lessons in our history.
