>>18137 (OP)
I'm solving this riddle as hundreds of generations before me, it's nothing special, however the more answers I have, the less I like it; not because the answers are not "pretty solutions" but because they are nothing positive at all BUT make sense.
On one hand you must admit that everything is set up in very beautiful way, it's incredible how some mechanisms of universe/nature work, in this context "life is simulation" isn't that much ridiculous thought, on the other hand, you do realize this instability of this all. Nothing is here forever, nothing is here completely determined but rather it follows non-obvious patterns of randomness, a lot of things went wrong, etc. The real trouble comes when you put it in contrast with this ever-loving ever-happy human views and realize it is just mere coping mechanism. Universe/nature is something very cold and very brutal, almost if not completely fascistic.
I really like the idea that - even no matter if this universe is just one of many - this whole structure is here as by accident, it just IS for no reason at all. It's not satisfying answer but it's the one I have easiest time dealing with. I would much rather like the non-existence in the most extremist way possible - there would be literally nothing, nothing would exist. When you think about this, you realize that something is not adding up because you can't truly imagine as if nothing would exist, ever. You can think about it as about "states of being", universe now is the same way as it could not be.
Of course, you can think more deeply about it and think that if universe has no observers, then the universe can not be qualified by anyone as existing, but whatever, I don't want to write essays about this.
