Language is a construct.

People do that part. Languages don't plan, they don't think. They don't _do_ anything at all.

Sure. Language just seems to structure a general learning system in a way that allows it to do all those things.

That's like saying python structures a general system.

Python does nothing at all. People use python to create constructs. We've covered this. :)

Python is not a natural language. A natural language communicates things that are not here and now (essentially everything that occurs naturally). Moreover, language can convey abstractions that exist because of language itself.
