It does not change my life in any way if an afterlife exists or not. No afterlife equals no worries of any kind. No pain no nothing. The end of what ever makes me up as a person.
If there’s an afterlife great too as I’ll find something to do for all those years. But considering time did not even exist before the Big Bang, nothing else could probably exist either.
So there’s little to no chance an afterlife actually exists.
But either way changes my life in no way.
