In the field of communication, we emphasize how important languages are (and mourn when they go extinct) because of their phenomenological value:
Each language offered a specific way of seeing the world by how they created shared meaning for various objects, experiences, or symbols.
I appreciate you affirming this from a historical perspective.
It is amazing to think about all of the languages that we don't even know about that stem from people and places that we can only imagine -- and yet, we are still part of their linguistic chain that has continually evolved even to today.
It is also interesting to consider how even these very old languages have evolved and adapt (and, sometimes, split to new languages).
