For someone who claims to be an open-minded skeptic, you sure are very ignorant of what atheism actually is. How can atheism possibly be likened to a religion? It is the *rejection* of a belief system, not a belief system in itself. When you ask for 'proof' of atheist views, it's like going into a courtroom and asking for proof of someone's innocence. It's absurd.
If I claimed to have an imaginary friend and you rejected my assertion, could I class you as having almost a religious belief in the nonexistence of my invisible friend? Essentially, that's all atheism is!
