Afterlife definitely exist as existence can't be destroyed. Maybe you will not be able to think or feel , but thinking or feeling are not the only thing that a person experience.
Also assuming someone thinks there is no afterlife , even then it is equally torturous as universe is definitely cylical (due to the problem of infinite regression ) , means you die - then quickly get reborn again in this universe again (as non-existence means nothing to you) , so basically you are caught in a cyclical loop of torture . If someone is chad , then it is good for them , but for incel it is infinite cylical loop of torture.
But anyway as per me afterlife definitely exist as existence can't be destroyed.
