>Surely I cant prove I will be the bernd of tomorrow
No you won't, since the passage of time, the present moment moving from one instant to the next, is an illusion. Tomorrow's Bernd is already there, looking back at today and wrongly believing he arrived there along with the present moment moving from today to tomorrow, as our intuitive conception of time tells us.
>One consequence I see from the scenario you are describing is determinism.
Yes!
>Another that perception doesnt reflect reality.
True also
>I am content living in my perception of reality, and not reality itself.
But I am don't! I must know that my berception is grounded in truth for it to matter
>Would you tell me what inspires such fear in you?
Firstly, if Eternalism is true, then the past is never gone. If there is a present moment that is moving through time, leaving the past behind so that it vanishes into non-existence, all the evil and horror in my life and in the world in general is gone once it passes. But if Eternalism is true, as science appear to say, then the past is just as real as the present and all the horrible thoughts and habbenings are still real, living reality and always will be.
Secondly, for many years I have thought that if the universe ultimately ends with the Big Rip scenario, which would result in a timeless universe, I have figured that it would cancel all of time and everything that has ever happened, undoing all the evil of this world. This idea is very dear and important to me.
But if there is no universal present moment (as our intuitive time concept would have us believe) traveling towards the Big Rip, reaching it eventually, then that just means that time spans from the Big Bang to the Big Rip (from what I have read it's perhaps 40-120 billion years altogether, but that is irrelevant here), but the scenario itself is never going to be realized, and time is never going to be cancelled the way I used to think it would be. This is not good enough for me because I want everything to be wiped away as if it never existed. For many years it was such a comforting belief that it would eventually happen and make everything right. But it's don't.
