Well... you know, it's not really implied by the game that Asriel can somehow magically move matter around to create physical bodies. Besides, that would be overthinking the entire situation. I think the simplest explanation is that the monsters gave those humans a proper burial. Kinda like Chara's. As for why they were inside the coffins and not buried somewhere in the first place... who knows, really.
The coffins were closed when Frisk encountered Asriel. They were open when the fight was over, after no time had passed, with everyone in the Underground having no idea what was going on except that ‘the human broke the barrier and we know Frisks’ name, somehow, or at least that there’s a human that’s not so bad.’
What do we know? Asriel was a literal god. He has been shown he can raise the dead in monsters. He I want to highlight this.again: he was a literal god, said to be all-powerful.
Suggesting that, in the minutes between when you start that fight and finish it, while most of the monsters are still part of Asriel, a funeral took place that nobody acknowledges, is somehow more likely than … Asriel doing for the humans what he did for monsters is a hugely complicated farce. Occam’s razor favors the simplest answer, and the simple answer is ‘Asriel gave everyone’s bodies and SOULs back.’
You’re overthinking the situation immensely and trying to play up your pessimism as rationalism, which I’m noticing is an ongoing theme with you. Your ongoing attempts to insert yourself into the theories and stories and ideas of both me and my friends have never been in the name of rationalism or fairness, but rather pessimism, an ongoing quest to find things that are least hopeful, have the least meaning.
If it’s positive, it can’t mean anything. Only negative answers, the bitter things, the unhappy things, the unsatisfying things, these are the only causes you champion.
But negativity is not more rational than positivity. Happy thoughts and hopeful conclusions are not less valid than negative ones. I’d thought that being so wrong about the storybook, which you insisted would not be about the story whatsoever, would push you to reconsider your approach. I can see I was wrong.
