I came across this; please inform me if this is the wrong subject. Old Pali documents suggest the existence of some trade routes that were operational at least 2500 years ago.
When considering ancient languages, it is nearly impossible to determine how they were communicated, as we lack time machines; thus, all our supposed "facts" are essentially theories. You might imagine early humans, or cave dwellers, using poor grammar (for example, saying "Me go find food."). However, I propose that there was minimal talking involved initially, with early humans primarily acting on instinct until they gradually evolved. Instead of thoughtless actions, they began to act with more awareness. Reflecting on the lives of cave families, I envision them engaged in conflict due to their limited abilities to think and communicate effectively. Over time, however, intelligence and understanding increased, leading to the development of unique languages across the world, diminishing reliance on primitive sounds like grunts or gestures. From what we've uncovered about historical language, it’s evident that linguistic evolution continues as we learn from our surroundings.
While I've presented this in my own words, I'm hopeful it provides clarity and inspiration. Wishing you a great day and good luck!
