Religion is an ambiguous term, which can be why arguments of this sort can get out of hand. To some, religion = faith. And I think you'll find that most faith has little to say about science (and in the case of your example says nothing about the earth/sun relationship). More commonly though, when referencing Religion you are really talking about Politics. Heliocentrasim, the crusades, Muslim terrorism, are all about politics, not faith. When you make an argument using the word Religion in a political sense, but others read it as attacking their faith, then things get very ugly. In other words you can be a devout Christian, and still consider the crusades to be awful. And you can be a good Muslim and consider 9/11 to be an act of war. Most anytime someone talks about religion as being the cause of war and conflict, the root cause is politics, not faith.
