Sorry, I’m answering myself because I forgot to post my own opinion.
I clearly have problems with any metaphysical explanation, because every one of them tells us to accept this Universe as it is, which seems arbitrary and, depending on the ideology, even cruel, and because we have no good reason to prefer an idea over the others. Do I believe in a god, gods, only matter; reincarnation, ascension, definitive death; simulation, real thing…? I do not know. Why would I pick one at random? If there’s something more to this existence, I’ll perhaps know when I die, and I will fight for our right to be better than we are right now because, come on, here on Lemmy we tend to be leftists, right? We do not like bigotry, exploitation, or unhappiness. We fight in our own ways against this. Then why would I stop when I die? If the ones controlling this reality are messed up, are we to accept the status quo and thank the tyrants that, at least, we were to experience smelling flowers although children were literally bombed next door? No. If they’re tyrants, heads must roll. Let’s be fucking spiritual punks! Not yet, just if we confirm this suspicion, lol.
Oh! Reincarnation, right. If reincarnation was real and it would make us cycle at random from one life to another, without anything else (no merits, no punishments, no learning, just cycling), I guess some lives would be better than others, yeah? But then, why? Is there a purpose? If not, what happens to souls that are tired of cycling? Can we opt out? If not, who or what is holding us against our will? Can we escape? Again, many questions, lol. But I finally answered!
