Reply #103: If you reject the existence of a spirit world, etc., then you "believe"

[TwilightGardener]

it doesn't exist. You cannot see it with your eyes, hear it with your ears, etc.--therefore it's not there. But, until relatively recently, bacteria and viruses "weren't there", or as someone else mentioned, radio waves. All I'm saying is, you can think you have solid proof based on your five senses and from lack of convincing proof from others, but until you can produce a tangible piece of evidence, then the spirit world's non-existence remains a theory, a belief. I included humanity because in MY set of beliefs, I believe that humans have a conscience, and have developed moral codes of behavior, for reasons other than simply evolution and peaceful coexistence. Perhaps you believe otherwise.
