Logically atheism is the right state of human mind's relations to religious tales: don't trust until proof.

Is atheism a religion? Definitively, no. Like health is not a kind of illness, like no-collection of stamps is not a hobby.

But I realized some special state of atheism, which can be recognized as beliefe in God. The second stage of belief.

What is the foundation of religion (like christianity or islam)? Right, the fright. Religion scares human with hell to make him reluctant to beliefs and to make him follow the commandments.

Believers are scared, very scared. And what if... what if to scare human much harder? Beyond the barrier he can handle it by his will...

Then, such a very scared human will start to believe in God's absence to keep his psychic unbroken. He will believe that God doesn't exist because he is very-very scared of hell and other God's "bounties". No God - no fright.

I don't think such an atheists are really exists, it's just a hypothetis.
