I would describe myself as agnostic, but I don't believe science has anything meaningful to say about spiritual/philosophical matters. Science is concerned with what's testable/measurable, we're not talking about anything testable/measurable.

I'll try explaining the whole heaven/hell thing again. What does hell look like to you? Is it millions of former people being tortured for not living a virtuous life? If you go to hell, what part of you goes to hell? Do the former people in hell have bodies and faces? Do the former people keep their memories of their past life? Do the former people still think like the people they once were as humans?
