Logically for me I was a soul only after I got here. How do I know that? Well first I have no memory of anything prior to being born. Nothing, not even a hint of anything. Everything I am has been formed here in existence. I have seen death here with others of us and in no fashion have I seen any existence of those souls after their bodies expired. Again, the logic in me has to admit that in context with all evidence, there is nothing as evidence to being a spirit or soul after death. This is where I have to admit that reality is my true living environment, so I cannot "believe" in an afterlife. Which kind of makes having a belief system for me rather moot.
Others say that I need a belief system so that I can understand and be regulated to be a moral person. For that I can honestly say that I don't need a concept of belief in order to be a kind and decent human being. It is natural within me to want to enjoy life with everyone else. I feel privileged to having been born at all so everything after that is wonderful. I find that my morality and ethics stem from within me as well as my curious nature. Anyone who has ever read my blog has undoubtedly been exposed to my acceptance that we all have compassion and curiosity as base natures so what we do with that as to moral and ethical thoughts and behaviors are truly up to us, without the need for an artificial construct to keep me "in line".
