One of the constants in the long clash between Scientism & Christianity has been the repetition & elaboration by the Scienticists of quite incredible myths & lies, that are still used in our public schools, media, &c, to mock & slander Christians & Christianity. I know about the potency of these myths & lies, for I myself was taught many of them, in school, saw them endlessly repeated in the press, heard them repeated by all liberal adults, & actually believed several of them until I came to riper years, & began to realize that public atheism requires the defence of a "bodyguard of lies." (And you will find them all repeated uncritically in Dawkins, Hitchens, Sam Harris, & all the current bestselling atheist tracts.)
Among the most universally taught & least subtle, lies taught to this day, is that Christians throughout the Middle Ages believed the world was flat; & that the Church taught this, & defended it as religious doctrine against Copernicus, Kepler, & Galileo. Yet the Church never taught the earth was flat, nor did any educated person, Christian or otherwise, ever believe it.
Indeed, the old Ptolemaic system -- universally accepted by intelligent Christians, Heretics, Atheists, Jews, Muslims, & even Hindus until the age of Copernicus -- was very clear on the fact that the earth was a sphere.
