If we all died and went to another world to start a new species, then we don't get to take our money, power, glory, and "bodies" with us. We would be reborn in alien bodies that look different. We do take our heart and mind with us which is what we use to animate our bodies. That means the beauty of animating our bodies is internal to our hearts and minds, not a part of our body. The beauty in how our spirit animates our bodies goes with us, not the beauty of our bodies on the outside. If we all start dying, how will your internal beauty be judged?
