Atheism is weaker today than ever. The image of atheism masks an even stronger belief.
I use a joke to illustrate: A man is in a psychiatric hospital because he suffers from delusions that he is not a man, but rather a grain of seed. After some time of treatment, he is cured from his delusions and allowed to leave. Shortly after leaving the hospital the man returns in utter fear. He says he could not leave the grounds because he saw a chicken on the road and was afraid of being eaten. His doctor tells him "but why are you afraid? you know very well that you are not a grain of seed, you know that you are a man!", to which to man replies: "Yes I know very well than I am not a grain of seed, but does the chicken know that?"
The vast majority of today's atheists fall into a similar trap, they believe God does not exist, but they are afraid that He does not know it. They unconsciously invoke God every time they speak.
