How I see it is that you are meat “matter” right now. When you die your meat matter is eaten by worms and flys (maybe). Some worms and flys then become part of the animal that eats them. Some of your meat matter becomes plant matter. You are not you anymore but you are now other parts of this earth. Obviously there is no consciousness that follows but your energy and your matter live on in different forms.

Edit: maybe there is a spiritual side that moves on a different path from the meatbag side which moves into a different vessel to experience life and the universe in a different way?
