Language has been around for the whole existence of life. For example humans in the stone age could communicate but it was very simple until newer, more complicated languages came in like Alexandrian Greek, Latin, Ancient German and Anglo Saxon. French is a Latin language (along with Spanish, Portuguese and Italian) that makes it one of the most complicated languages to speak in the whole world because it has strict pronunciation compared to the languages in the stone age that are easier than French.
Writing was first done in Egypt in MMMXL/3400 BCE was the first hieroglyphs ever recorded which was simple compared to the later egyptian hieroglyphs and the english writing is way more complicated because you have different spellings for the same word for the past, present and future. In the stone age they didn’t even have a writing system until the neolithic age of human technology was discovered for example writing and better weapons.
I came, I saw, I conquered
