People come and go, they come into the matrix and they move out of the matrix and really there are just few possibilities – afterlife exists and afterlife does't not exist.
When you move out of existence – there's no longer you. You simply go to that place where you were before, but if you could come into existence one time, who's to permit you coming the other time?
Since experiencing life is only possible through one subjective consciousness, who's to permit you from the next and the next experience?
Afterlife is the trickiest question of them all, since you can't possibly know what's happening when you're out of existence.
In my humble opinion. the self never dies – it moves from one shape to the other almost in an instant, because when you're dead there's no time and no space.
Somebody has to experience life, when there's no you – who experiences life?
Everything is created when we are born in an instant and everything is disabled when we die.
Further to note, we seen only objective deaths so we don't know what's happening on the inside.
Eventually we will find out.
