AGNOSTICS (the word means "don't know" or "uncertain") are those who hold that we just cannot KNOW (for sure anyway) if there is a supernatural and if so, what that's like. I think they are just "stuck" in the presumption that if it's not a part of the physics we know, then we can't know it. I "get" it (although I consider this a "small" and not altogether logical assumption). But again, I get it. And I know a good number of folks who are agnostics; indeed a goodly percentage of my fellow physicists are agnostics. These people have nothing against theists... no negative feelings or conclusions whatsoever... they may even hold that theists have a comfort and motivation that they hold in some esteem; they just feel that those are working with an assumption they can't prove by modern physics and, as agnostics, they don't "go there."
ATHEISTS (the word means "no god") is a religion since it's based on a proposition about the supernatural. They aren't "uncertain" no, they are as certain as the theist - just holding to the opposite position. Of course, they can't "prove" their position via modern physics anymore than the theist can but they insist that their position needs no substantiation. Okay. I've not personally known any atheists but I've encountered a few online. With some exceptions, they seem angry and very passionate in the desire to destroy any embrace of anything outside the contemporary understanding of physics. They tend to be anti-faith, anti-theism in a way that is very, very distinctive and different than (sometimes even opposite from) what we see in agnostics. Why? We can only theorize. We'd probably need to ask Dr. Phil, LOL.
