People that have only ever spoken one language might just assume that the books that are in their language are the only ones that matter to the world. A big part of the reason what that is the case has to do with the fact that we all live in bubbles at any given point in time, and these bubbles make it seem like our culture and language are the global standard. The thing is, other languages do exist in some way, shape or form and most of them have works of literature that are so incredible that you would be moved to tears by them or you would have your jaw drop in wonder at the fantastical worlds that they end up portraying.
The kind of books that other languages are created are quite remarkable. If you read full post, you would see that world poetry is quite amazing as well. While long form prose is not quite as common, poetry has been a mainstay of literature for thousands of years. In fact, epic poems might have been the first kind of literature that was ever recorded, so if you look into it you wouldn’t just get an entertaining experience but rather you would get some kind of a glimpse into the way things used to be as well which is obviously going to be amazing for you.
The world is full of literature that you can’t even imagine, and libraries started to broaden their horizons by adding more world literature then the world might just end up becoming a more cultured place. All of us need to start sharing our cultures with each other so that we can become one species.
