Yeah yeah, we all hear this story in gradeschool. However, let's hear what a noted historian of Science has to say on that issue:This book is partly responsible for the long atrophy that froze Western civilization, during centuries of scholastic babblings. Anything that was interesting within the Western antiquity period, the birth of science and philosophy, was almost destroyed by early Christian attempts. Those fanatical, intolerant savages waged a war against intelligence that lasted during centuries.
“The contribution of the religious culture of the early Middle Ages to the scientific movement was thus one of preservation and transmission. The monasteries served as the transmitters of literacy and a thin version of the Classical tradition(including science or natural philosophy) through a period when literacy and scholarship were severely threatened. Without them, Western Europe would not have more science, but less.”
--David C. Lindberg The Beginnings of Western Science: The European Scientific Tradition in Philosophical, Religious, and Institutional Context, 600 BC to AD 1450 pg.157
As for the rest of your post, it's not worth bothering with.
