"Language" 50k years ago? Spoken? Written? HOw many words do you have to have to make it a "language?"
You'd better define what you mean by the term a bit better!
There's no evidence that would really be able to pin this down very well, with evidence of symbols going back 8-10,000 years ago at least but that's written language, something designed to merely make permanent spoken language. It is clear that the areas of the brain that focus on language as well as the physical ability to create "words" goes back at least to early
homo species.
There's also the fact that language can be described very broadly to include what most mammals do with their voices at at least a simple level, and even bees have their "dance language" which is inarguably a mechanism for communication!
The more elaborate our means of communication, the less we communicate,
