Christanity conbtributed to advance of science? Just an opposite of historical truth.
In medival era, Christanity was prime hiderance of advnce of science.
In that era, Arabia of Middle East was far ahead of Europe in science, math, astronomy, chemistry, literatures.
There was no notable scientific advancement in Europ in that time. That is why we call the era of Christanity domanated Europe as "Dark Age".
Christan faith and its insane passion was prime cause of medival "Crusade" war. So it shuold be easier to make a war using religious fever of Christanity.
Chirstanity should be -10% science, +2 happniness, -10% Military Unit production cost.
Isam should take +10% science advantage. Once the influence power of Christanity weakens in Europe at end of medival era, advanced scienctific knowledge and cultural heritage preserved by Isam people during the Dark Age had helped Europe to wake up from Dark Age and reach to Renassance Era..
While at one time the followers of Christianity were behind technologically, it wasn't necessarily directly caused by religion (although the church didn't help much).
The reason that Europe (and hence, Christianity) fell behind was that the Roman Empire fell apart for good in the sixth century. It (Europe) was brought out partially by King Charlemagne in the eighth and ninth centuries. His reign brought safety to many of the old trade routes and allowed information to once again travel. This opening up of the old trade routes allowed Europe to catch up technologically.
The real reason that that those of Christianity eventually took a commanding lead over most of the rest of the world (remember that the Chinese were still isolated by their own rulers) was that Gutenburg invented the printing press. This is typically noted as the time of Europe's complete emergence from the dark ages, although they had been pretty much safe for a couple hundred years by now. The printing press allowed that information no longer had to travel from place to place by word of mouth. It also meant that the wealthy, once the sole owners of the world's handwritten books, were no longer the only people who had access to information and technology. With information available to more people the ideas began to flow.
The Chinese are actually the ones who gave Gutenberg the idea for the printing press. In fact, they had developed the printing press earlier, however they used wooden blocks which would deteriorate quickly. Despite the fact that the Chinese had a commanding lead in iron working, they never got the idea that iron or steel could be used as print blocks rather than wood. Since the wooden blocks weren't really a viable option, the Chinese eventually gave up on the idea. The Chinese system of writing using symbols rather than letters also didn't lend itself well to block printing, which further complicated matters.
While one could certainly make a case that there were instances where the Christian Churches held back new ideas, you could say the same about any religion. Some Islamic sects keep their women out of the loop, so to speak. That's half of their population that is not schooled and is unable to add to the technology count, as it relates to Civilization terms.
My point is that it wasn't Christianity that held Europe back during the dark ages, it was the insecurity of Europe and their system of Lords and Serfs. Having no true leaders, most Europeans turned to the church. The church is about worshipping a higher being; not about discovery. Christianity had little to do with Europe's laspes during this time.
