Thanks. Interesting article.
OK, I think follow now.
I wouldn't say atheists don't exist, but that they have the same neuroanatomy as believers and magical thinkers.
We all have basal ganglia and limbic systems, with quick response short cuts, on speed dial. We're apophenic, perceiving patterns, faces, intentions and relationships where none exist. We're threat sensitive. These are limbic responses, and we're all wired for them.
Intellectual skills, like reason, logic and analytical thinking are neocortical. They're learned, slow, deliberate and, till relatively recently, pretty useless from a survival standpoint.
Reasoned conclusions like atheism can't override our deep seated emotional responses. I may know intellectually that I'm securely roped to a tree while looking over a cliff, but I still get butterflies in my stomach.
