I would like to point out the fact that as a human being, with the personality "god" supposedly gave me, I find it unreasonable to "let go" of not only what I find true in science, but to what is obtainable through the human senses, because I can not be sure that a "spiritual" aspect exists outside of the human imagination. And if a god wants me to do so, I will not, because if a god created my own logic, and created something illogical (i.e.- "spirituality") I would take that as him wanting me to either believe or disbelieve in "spirituality." And since I disbelieve it's existence, my action is justified, based on what reasoning he gave me.
