Arguments for why an afterlife would be hidden?
I don't remember starting this conversation, but I think I was assuming an existence that doesn't interact with the physical world in a way we can detect. And I'm assuming we can't detect much if our thoughts on the origins of the universe shift a lot each time we get a new telescope resolution.
As far as things having real meaning I don't consider only now in which I can feel a sense of pride for what came before, but also the knowledge that any knowledge or perceptions during this life could be voided out upon death making any previous perceptual functions exist as little after as before, so what makes them important during. Without a clear purpose what can we know, and with our lifespans being virtually nothing compared to the duration of the universe how can we even determine themes and patterns.
