Where Are The Bukhari Manuscripts? Bukhari Had Loads Of Students, So Where Are their Writings?

Because Jesus and the Apostles actually existed, people would obviously write about them and we have examples of those writings from many different people. If Bukhari was real, then we would expect the same thing about him and his students, but this information seems to mostly be missing and it is as if people instantly destroyed their writings after they were produced, or the more ovbious answer is that Bukhari is just a made up character.
