No, not a religion, but a belief. By definition religion needs a deity, a spirit or afterlife, so we can exclude religion from equation. Some atheists might need some help in this department to belief that supernatural world doesn't exist, especially if something freaky-improbable happens.
Generally speaking atheism is not believing in supernatural. A clean slate of mind in department of religion with nothing written on this slate, state 0. Atheism is not believing, in lack of evidence for existence of any supernatural, gods or spirits. As we know proof of god existence lies on a claimant.
In my case, I used to believe in god, then I lost my faith, therefore I became an atheist. I didn't change one believe for an other, just lost a belief in god.
The question: Is there a creator and is the universe constructed in an organized manner, is answered through the scientific method. The creator could be the energy holding things together in space, creating and maintaining equilibrium. Whether we personify God or view God as a scientific construct makes no difference. In essence, my existence depends on IT to survive and so does every other living entity.
There is method in everything we observe whether we believe it is created or because of natural occurrences is a matter of world view. Personally, I believe things make sense in the world because of the existence of a creator. I cannot accept the belief that nature works the way it does simply because of natural processes were it not for the existence of a creator exercising control over such processes.
The argument that we have no scientific proof for the existence of God or a creator is in my opinion one of the greatest fallacies in 'scientific' reasoning. The question however of whether a creator exists in man's image, whatever that means, is another question altogether. I believe that suffering and disaster is part of nature's process. To lose faith in God because of the disaster and suffering in the world is blaming the creator for our irresponsible actions and the consequences of our past actions on the planet. If intelligence and assuming responsibility for one's own actions were commensurate then I would have said that you have a point however it is my personal experience that levels of narcissism increase in more intelligent individuals as they work much harder to achieve positive regard from others, seeking recognition and affirmation by their peers. In essence, a high IQ suggests that an individual spends the requisite amount of time studying and developing themselves in the belief that they would be able to make a difference in the world, hopefully a difference for the better.
What you are saying is that less intelligent persons need to believe in a creator whereas I am saying that more intelligent persons need the existence of a creator to avoid personal responsibility for the suffering they have caused. This however becomes too 'painful' for some individuals to bare, the elite or exceptional among us have come to the realization that belief in a creator does not negate their responsibility and in an effort to free themselves from the burden they rely on themselves for 'salvation' ... the theme here is CONTROL.
Intelligence is correlated strongly with a belief in an individual's ability to exercise control. This in turn correlates with self-aggrandizement or narcissism. The belief that there can be no creator is found among the most narcissistic individuals, those of us who refuse responsibility and rationalize that the proverbial creator would never allow the holocaust to happen and yet they believe that man would somehow stop the suffering he has imposed on his fellow man. This circular reasoning ends at the feet of the individual narcissist ... for lacking the necessary empathy and insight to perceive their own inability to comprehend that it is man's own responsibility to behave in a manner that is in alignment with their own 'ideas' befitting the existence of a creator.
If we as man behave poorly and expect somebody other than ourselves to clean up our mess, does that not say more about our lack of morality and misguided self-importance than the existence or non-existence of a creator???
What if a creator had no reason to save such a man as ourselves, does that mean the creator does not exist, or that man is riddled with vice and self-love?
