Christianity produced what in 2000 years? Name a Christian era that compared to those of Muslim Spain or Baghdad:-
When the West stopped believing in Christianity [earth centre of universe, witchcraft etc], it was able to come out of its dark ages. They built up India in the same way that the Romans modernised areas they ruled, to help control the population [Roman aqueducts can still be seen after 2000years].
We are now in our dark ages with thinkers/reformers telling us to go back to the Quran if we want a better life; how many people are calling for a return to the Bible to do the same?
