Metaphysics is a young man's game. It all leads to nihilism. That happened to me, and I was heavy into metaphysics and existentialism. The only thing that you can definitively prove is that something exists. That something could be a dream, a hallucination, anything. You know that something exists because you are reading this post right now.
Then you can go the next step and realize that nothing can't create something. So if something is here, which we already proved, there was never a time with nothing existed. Something has always been here. There was no start or beginning. Then you can take it a further step and realize that if there is no beginning, there is no over-arching time. If there is no time, then things that require time can't exist. That means that nothing can change or evolve.
Everything that could possibly happen is happening right at this moment. Everything. I call that absolute infinity. Since every single thing possible is happening there is no good or bad, they are all a part of absolute infinity. You are doing all of the "good" and "bad" things right now in absolute infinity. Nothing you do matters. You've already made that decision, you've killed people, you've loved, you've done everything.
Once you get to that realization, you can finally move on to other things. Metaphysics and existentialism go nowhere.
