There is no way to convince a person who has a certain worldview that they are wrong simply by saying so. Spirituality has been bulldozed by western culture and this is handed down from generation to generation. Because hard scientific proof is not available (for either side) materialists have run the show for some time. Ironically, technology is providing evidence, that what you see is not what you get.
As to your last comment......This is it. What is reality, and how do you know 2 shakes about that proclamation and whether it gets any better or not?
