Instead of nihilism, Nibbana is the only thing that exists

Well, once upon a time this was discussed a little, here on the site:

There, Vstakan talked about it the way I think about it; here is their example:

There is, firefighters, a not-hot — not-blazing — not-kindled — not-scorching [extinguishment of fire]. If there were not that not-hot — not-blazing — not-kindled — not-scorching, there would not be the case that escape from the hot — blazing — kindled — scorching [fire] would be discerned. But precisely because there is an not-hot — not-blazing — not-kindled — not-scorching, escape from the hot — blazing — kindled — scorching is discerned".

Nibbana doesn’t exist just as “not-fire” doesn’t exist.

(Just for kicks, here’s an article similar to the OP: https://puredhamma.net/key-dhamma-concepts-that-have-been-hidden/nibbana-2/nibbana-exists-but-not-in-this-world/

I think both are …off-target.)
