If the world didn't have these problems solved before now... there aren't demons in the physical world unless you are talking about evil beings but the world connected to this world has demons doing the most horrible things in this world leaving humanity nothing but to be reaped, cropdust a field and kills some people and there is an equivocal demons doing an evil act and they enjoy doing it like demons in hell, we went to hell but there are still things to enjoy, not what reality should have been, you can either tell me we went to hell or we're in a random world that spontaneously exists and it's coherent and can get very advanced I don't know why have a world like this I'm talking about worlds out of the physical world not this world that is fundamentally flawed you can't do much in this world because you need hospitals and have energy limitations, should be more magical and more like a good dream
