wikipedia wrote:Science is an enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the world. An older meaning still in use today is that of Aristotle, for whom scientific knowledge was a body of reliable knowledge that can be logically and rationally explained
Doesn't exactly line up with the wikipedia definition of religion, to me.
Also, would you classify science as a philosophy? Because it looks like the only thing that would make it not a religion at this point is your caveat of believing in God(s), which would then make it a philosophy. Unless you have some other way of designating these things.
For me though, it's quite simple. Science is a process, whereas Religion is a belief system. One can identify as a particular religion, whereas someone can't really identify as a science believer. This is where atheism ends up being thought of as a religion, because when someone asks what religion an atheist is, they say "oh, I'm an atheist."
