agnostic was coined by t.h. huxley to mean, without knowledge of things unknowable. to say you are an agnostic is the same as saying you are an atheist. either way, you are saying that you can not know that there is a god. now, there are different forms of this belief. some say they are agnostic in the sense that they are not sure, now, they might want to believe that they are not atheists, but they are de facto atheists. the reason, they do not believe in a god. if you do believe there is a god, you can not be an agnostic, because by definition, to be agnostic is to claim that you can not know if there is a god. with that, claiming that you know there are things such as god, or a spirit, or a spiritual world, is dumb.
