hi in minecraft i want to try downgrade survival here is how it would work that I start in the latest version and downgrade to older versions overtime I think it would be fun what do you think
sounds like a fun idea, but the versions of minecraft are so different from each other, especially if you go back to older patches. It would probably crash a lot too, and you would have to skip some versions. having the versions go forward instead of backward seems like a better idea, but even then things might get weird.
loaded a minecraft world made in 1.12.2 in beta 1.5 and it loaded fine but there was a mesa biome before i downgraded when i loaded the chunks of the mesa biome the game immediatly crashed
Worlds created in any version since 1.13 can't be downgraded at all, even by a single version - all chunks loaded in the older version will be reset because they don't recognize the "data version" of the chunk and/or many changes are constantly being made to the chunk format and newer versions don't appear to have any sort of "remove invalid blocks" methods (for example, the code for 1.6.4 has a method named "removeInvalidBlocks" which will set unknown blocks to air, and unknown biomes are converted to plains).
Older versions are more forgiving but at the very least you will lose unknown blocks, items, and entities, and in some cases, all items and tile entities and/or their data (e.g. 1.11 changed the names of tile entities and made them all lowercase so "Chest" is now "chest", which is not understood by 1.10 (the ID is case-sensitive), so it will discard the tile entity and its data (chest contents). 1.8 changed item IDs from numbers to strings so all items will be lost when downgrading from 1.8 to 1.7):
In the case of downgrading from 1.7 to 1.6.4, the 1.7 biomes will be changed to plains in name and foliage color but will not disappear (aside from unknown blocks like 2-high plants and dark oak and acacia leaves and wood; 1-block high flowers and new stone types will turn into roses and normal stone respectively as 1.6.4 simply handles invalid data values as the default):
(I actually used a mod that added mesa biomes to 1.6.4 but the same applies to 1.7 biomes; I also once loaded a 1.7 world in 1.5 and a mesa biome turned into a big stone basin full of black lighting glitches)
Also, I doubt you actually loaded a world created in 1.12 in Beta 1.5 because Beta 1.5 used a completely different save format; chunks were saved in files with the extension ".mcr" while versions since 1.2 use ".mca", so Beta 1.5 wouldn't have even tried reading them (Beta 1.5 can however probably still read level.dat, at least in part):

What kind of downgrade are you loking for?
Removal of newer items/mobs and resources.
Change in game mechanics?
Limit your options over time?
I've seen an interesting challange once on youtube,
where the two players had the worldborder very close to spawn and water rising every view minutes.

I am gonna stay in modded 1.12.2 untill my potato dies. No mercy! :Q
one question if you make a full set of iron armor and tools in 1.16.4 but then downgrade to 1.12.2 will your gear and blocks you placed still be there
Maybe for the gear if it is in your inventory but definitely no for anything you placed in the world - the save format in 1.13+ is completely different from earlier versions - you may as well be opening an image file in a text editor or vice-versa (you'll either get gibberish or an error):
I tried out my world on 1.13 and everything was fine. I went back to the 1.12 version because it had Optifine. However, when the 1.12 world loaded, all of my creations were gone, there was not a trace of anything I had made since day 1
The same is true for any version since 1.13, either due to changes to the save data (e.g. 1.15 changed the way biomes are stored) or being unable to recognize the data version of a chunk (only versions up to the current game version are recognized):
I have a building testing world, and decided to update it to the 1.15 snapshot for the new blocks. However, I tried downgrading it by playing it on 1.14, which just results in the entire world getting reset. I didn't make a backup, so I lost everything.
(there are unfortunately a lot of stories like these, often with no backups; at least Bedrock Edition was properly coded so it refuses to load a world loaded in a newer version but Java Edition only has a message that asks you if you really want to load the world, and only in newer versions)
ok thank you i made a world in 1.16.4 and then loaded it in 1.12.2 and the game crashed
i was however able to successfully load the world in 1.7.10
There is no way you could have possibly loaded a 1.16.4 world in 1.7.10 with no issues - try placing some blocks and they will disappear because the chunks will have been reset, which will also be obvious if you take screenshots before and after (trees, grass, flowers, etc will change because they are placed differently). Any items in your inventory will also disappear (same for any version after 1.7.10 since 1.8 changed all item IDs from numbers to text and 1.7.10 has no idea how to read them, much as 1.13 changed the way blocks are stored in chunks) so it will be as if you'd created a brand-new world - there is simply no way to downgrade past 1.13 and keep anything unless you use a special tool designed to convert save formats and I don't know of any such tools (either way, you still can't transfer over things that don't exist in the older version unless you use/make a mod that backports them but then you aren't really downgrading, or replace them with the closest substitute).
Apologies for my naiveté, but why? Why not simply load the game in the older version to begin with? What possible advantage/challenge does this present?

You certainly can upgrade a world to newer versions, starting at least as far back as InfDev; the game will automatically make the necessary data conversions when upgrading, though it won't maintain continuity with previously generated chunks (this is why the same seed generates a different world in Alpha and 1.16) and in chunks created prior to 1.2, biomes (vegetation color and precipitation) will change since they weren't saved until then. There will also be a few oddities, such as leaves changing to different types as new leaves are added, due to changes in how the game stored their states (you can use this to your advantage as you can get new tree types without having to explore new chunks), and sea level was changed from 64 to 63 in Beta 1.8 so you'll get a 1 block drop off into new chunks (of course, you'll see much bigger cliffs due to changes to terrain and biome generation, which also changed in 1.2 (only biomes and biome-dependent terrain, so you may not see sudden changes everywhere), 1.7 (completely changed), and probably a few times in InfDev-Beta).
I did some playing around in a 1.17 snapshot on my creative world, and when I went back to 1.16 the new blocks were replaced with air, but strangely the dirt they were placed on never turned into grass.

I guess there must be some memory left, the game can't interpret.
Like information about "there is a block on that dirt".
Have you checked the blocks with f3 screen, what are their light levels?

I can't find these blocks currently as my creative world is quite large. I know I was building with note blocks, dark prismarine, and the 1.17 materials. Is there a way to search for note blocks or dark prismarine with a command?
I found it by wandering around the creative world further. Here's some information:
-The dirt is now grass
-The grass the blocks used to be on varies from light levels of 5 to 0.

Depends on how far back you want to go. Trying to use newer worlds with older versions of Minecraft is going to lead to all sorts of problems.
Semi-related: Capitalization and punctuation are your friends.
like downgradeing from 1.12.2 to 1.11.2
loaded a minecraft world made in 1.12.2 in beta 1.5 and it loaded fine but there was a mesa biome before i downgraded when i loaded the chunks of the mesa biome the game immediatly crashed
If you did that you would probably run out of versions depending on the speed
i told my friend about the idea and my friend said if i did that the moment i downgrade the world would immediately get corrupted
