If you see atheism as a belief then there is a similarity as there is no proof of atheism as you cannot prove a negative, that there is no God. Atheism is a belief, an erroneous one in my estimation. I think that atheism is not motivated by reason but by a desire to escape morality.
(The old atheists are immoral/ammoral argument)

One of the problems with materialistic atheism is that it is narrow-minded and dogmatic in closing itself from knowledge that does not conform to materialism and naturalism. We are more open-minded. We accept there is knowledge derived from scientific testing and reasoning. We are entirely willing to accept material and natural causes but we admit the possibility of other ways of knowing.

As atheism operates within naturalism and entirely depends on it it cannot admit the possibility of other ways of knowing.
