Are there really Atheists?

"I surmise that religions, like languages, evolved with sufficient randomness, from beginnings that are sufficiently arbitrary, to generate the bewildering--and sometimes dangerous--richness of diversity that we observe. At the same time, it is possible that a form of natural selection, coupled with the fundamental uniformity of human psychology, sees to it that the diverse religions share significant teachers in common." -Richard Dawkins, The God Delusion

I found Albert Mohler's commentary on The God Delusion interesting:

This is what it really comes down to:
The only one who could say that there are no gods of any shape or size in the universe throughout all time is God Himself. A person would have to be in all places at all times with all knowledge in order to be able to say “there is no God.” (The Blind Faith of Atheism)

“The fool has said in his heart, there is no God.” -Psalm 14:1
