Atheism

For me, atheism is a very simple thing. Once you establish that all religions have an equal claim to the truth, you are left with the option to either pick one, which leaves the dilemma of certainty, or there is the choice to worship a non-specific deity - at which point, the question follows, if this entity wanted to be worshipped, wouldn't it have been so clear about such a thing, that no one would be able to argue and there would only be one religion?...so if this non-specific creator entity doesn't care enough to leave all people with no doubt as to its existence, it either doesn't exist, or doesn't care.
