I think that, once again, we are trying to modify reality and subvert definitions.  Agnostic is a scientific term when used in this manner.  An agnostic is unable to prove the existence of something.  Thus, it is a common religious dilemma. Thomas Huxley first coined the term for scientific purposes. Charles Darwin is a good applied example, since he wrote extensively about his religious agnosticism.  There is nothing inconsistent about being a religious agnostic; it is not at all close to being an atheist.
