No, my native language is Spanish (LATAM/Castilian, not Spanish from Spain). However, I've been writing in English on the internet for about three years now, so I've learned a lot. However, I feel that I still have much more to learn about this language; I still don't know how to speak it easily. 😅

And yes, you are right about what you say about infants crying. Before language there were also signs, drawings and facial expressions. I also know a little sign language because my grandmother is deaf.
