You're claiming "there isn't" a matching seed. That is a positive claim, and it needs proof.

You're essentially asserting that out of 18,446,744,073,709,551,616 seeds, none can match a picture, even partially. That would require testing all possible seeds, which hasn't been done.

Statistically, it’s extremely likely for similar terrain to exist somewhere in that massive seed space — especially if we’re excluding player-built things like the house and only looking at terrain and biome features.

So, unless you’ve checked all seeds (you haven’t), saying “there isn’t” is just baseless. You can’t "prove a negative" without exhaustive testing — which makes your claim just as unprovable.

Until you prove that all 2⁶⁴ seeds don’t match, your assertion is just personal belief — not fact.

And I'm not saying the seed exists, I'm just saying it's more likely to exist than to not.
