Find the seed of the world, please help me out here

You clearly don’t understand how difficult that is, it took like 300 people like 4 years to find the seed for the og minecraft panorama, the 360 view of the entire landscape.

my dude. due to the size of a Minecraft world, you need VERY specific details to find a seed. this image could be taken from nearly any world.

Next to spawn, I think I remember you spawning in either a plains or savanna biome, and next to it is a desert temple with no chests inside. It's been so long I can barely remember the details.

This is the last image I have of this world left

There's also a large ravine near a village with the stronghold inside it

Do you have a Backup maybe ?

sorry to tell you, it's not gonna happen. there are 18,446,744,073,709,551,616 unique Minecraft seeds, all of which likely have something like this somewhere in the world. Of that, there are probably thousands, if not millions, of seeds with plains/Savannah and a ravine village with a stronghold near spawn. It would take a dedicated team of seed searchers years to find it, especially when it's based on a single screenshot.
