Wow. I didn't see this thread earlier. I confess I haven't gone through the whole thing yet. I always thought agnostic meant that you feel there is no way to know whether there is a god or not. I feel like there is a way to know one way or the other, but we don't know what that is yet. That said, if we knew how to, I think we could confirm there is no god. We've nearly done so already.
