Whether there is an afterlife depends on a whole environment of stuff. What you are seem to be saying is are glassy cherries nice - No, therefore baking does not exist. It ignores so much that it really is like looking at the universe with a microscope. Step back, forget introspection. How long is "now" that never ends. If you could pick one second of life where you were ecstatically happy, and that never ended and never palled because there is no time within which to pall, would you reject that? Stop thinking in a vacuum and start observing.
