> Why so? Because it can't be proven either way. An atheist who claims to know for certainty that there is no god is expressing a religious, faith-based viewpoint. I guess that isn't necessarily at odds with being an atheist, but part of why I'm an atheist is that I try to avoid believing in things that aren't provable and don't fit existing evidence. > If we go for that, sure, we cannot be sure of anything. We can be sure of things that have been proven using the scientific method. Certainly we can't be 100% sure, because that method is applied by fallible humans. But it's silly to suggest that levels of sureness don't matter; I can be more sure about the idea that we don't live in a giant ice cream than of other things, and that's fine. But I think it's true that we can't really be sure of anything... and that's also fine.
