I think a lot of is because people no longer pay attention to their own mortality (and by extension the after life). I’ve even had some twenty somethings tell me, in all sincerity, that they won’t die because by the time they get old, “Science will have figured out a way to stick your brain in a computer so something.” If you honestly don’t think you are ever going to die, then by extension you are not going to be worried about what comes after.
