On the actual game, we already had a discussion on it a while ago:

Anyways, on Science and Religion.
Religion most certainly hindered the progress of any thinkers, which includes scientists. It is due to the fact that people are generally afraid to be wrong, and prefer the security of certainty rather than the fear of uncertainty. Martin Luther, was one who certainly disagreed with the accuracy of this "certainty". Essentially he found no peace in following the established rituals, seeing that no matter what he did he could not seem to reach God. Anyways, around the time of Luther, Christianity began to break down in Europe, and this would eventually break the bonds holding back the advancement of great thinkers of Europe. By the 17th Century, Europe was a very different place than Europe under the Roman Church. Of course, by this time a new major demon had shown its head, nationalism, but nationalism did not hinder scientific advancement very much in Europe.
Anyways, it is true that most scientific advancement occured in Christian nations, but a more accurate statement would be that most scientific advancement occured in nations of Germanic stock.
