It's really surprising to me that we have these language fragments that exist without any samples referencing the language itself.

I suppose for very young languages there wasn't a lot of need to specify that something was written in one vs the other given that any reader could just plainly see it with their eyes and perhaps didn't have a lot of cause to have "well, in Russian they X whereas in Japanese they Y" conversations.

But like...imagine a remote future in which we have only SMS fragments that read "you dtf" and "sup" and this weird purple thing with a green tip we're certain was a vegetable next to what we're absolutely convinced is a rendering of a butt and that's the entire corpus of the ancient XIZZY103.4 langauge.
