Answer:

When we die, our spirit and body separate. Even though our body dies, our spirit—which is the essence of who we are—lives on. Our spirit goes to the spirit world. The spirit world is a waiting period until we receive the gift of resurrection, when our spirits will reunite with our bodies. Our future resurrected body cannot die and will be perfect—free from pain, sickness, and imperfections. It is because of the infinite love of Jesus Christ that everyone will be resurrected.

It may be more useful to view life as a totality rather than focus on its component species, individuals, cells and molecules to understand its profligacy. In order to survive challenges, those components need to thrive when times are good. This generally means prolific reproduction often involving production of seeds and young way above replacement rate. Then because we ultimately all share the same biology we all become food for others, or at least we did until humans become powerful enough collectively to imagine a “safe” exemption and started to bring the whole show crashing down on a scale equivalent to other increasingly well understood mass extinction events, each seemingly with their own unique combination of triggers. Since complex multicellular life became possible with higher oxygen levels after the end of Snowball Earth, life itself has recovered its rich diversity after each mass extinction in of order ten million years. But as the sun gets ever brighter, water continues to be lost, and our rotation slows towards tidal lock, all astronomically slow processes compared to even plate tectonics, we have no reliable knowledge as to how far planetary conditions need to change before reaching a point of no return.
