Your conclusion is impressive. I only had to change one reference from it so that your perception could be better intepreted by me:

"The reason why we are able to have a written and verbal language is not because of any sort of ingrained understanding or even specific knowledge. It is because we all have very similar sensory capabilities, and although we don’t always interpret things the same, or create each thing we see in exactitude, we do have sufficient numbers of commonality to reference which allow others to interpret what we perceive into something they can understand."
