Great comment. I am tempted to continue the conversation.

Instead, I will finish by saying that, in my view, any system of belief seeking to describe the nature of reality that relies primarily on faith to provide certainty is a religion. Favouring faith over evidence is especially qualifying.

I would consider many of the atheists I have spoken to or read about to be religious by the above definition.

Many of those famous for being atheist certainly meet the criteria. Richard Dawkins has said that he “believes” science can answer any question despite science itself saying that it cannot ( Bell’s Theorem and Godel’s Incompleteness Theorum for example ). PZ Meyers has gone as far as to say that there is no evidence possible that would convince him that God exists ( even Jesus appearing before him I recall ). If that is not religion, I do not know what is. It is certainly not science.
