Religion and Spirituality Are Vague

Philosophy is not constrained by the requirement of only dealing with empirical data and knowledge. It's also about a priori knowledge that is independent from experience, for example, intuition. Philosophy does not carry the burden of needing to be falsifiable. Multivers theories are also not fable. Therefore they belong in the realm of philosophy. Now, religion and spirituality are all about belief. They are mainly about belief. And it's not only about belief, but a andd we don't even know what spirituality is,. So there is no real definition of spirituality.
