Okay, so two of my friends--one is agnostic and one is atheist, where having a discussion. My agnostic friend was like atheist "believe" in something because they believe that evolution is true. And that And agnostics believe in nothing, they really don't believe any theory is necesarily true concerning the creation of the world. I only sort of understood where she was coming from. So can someone clarify the difference between agnostics and atheists?
