This can be answered though, albeit imperfectly. On a more reductionist level, we are the cosmos experiencing itself. Now there are many ways to approach this. But just providing us with the right chemicals to feel pleasure/satisfaction is a step backwards. All the evolution of a human being, just to end up functionally like an amoeba or a bacteria.
So we need to retrace our steps backwards in this thought process.
I could write a long essay on this.
But, to exist in first place, and to keep existing against all the constraints of the universe, is already pretty fucking amazing.
Whether we do all the things we do, just in order to stay alive and keep existing, or if the point is to be the cosmos “experiencing itself”, is pretty much two sides of the same coin.
