It is easy. Spirituality, and even spirituality uses forms of science, none that you will agree with of course because your personal beliefs sway your judgement. Its a trick question really, you think everything that exists can be explained by science, so that pretty much only leaves the supernatural, which you'll reject because science cannot explain it. So you will forever live under the illusion that you are poking holes in peoples bubbles yet you are the one in thIe bubble because you are dependent on the limited knowledge of science. So with your question, the only option is the supernatural, and like it or not, it has value. Science is the B team and spirituality is the A team =).
