the root of all modern languages

the whole universe used to speak it

uhhhhhhhhhhhhhhhhhhhh

P.S: the closest thing to that is Egyptian, but not the language, the Alphabet (the Symbols, not a literal alphabet). Tons of alphabets are descended from Egyptian, including, but not limited to: Greek (and by Proxy Latin, Cyrillic, Georgian, Armenian, Armenian and Armenian (I just noticed this, I'm leaving it in because it's funny)), Arabic (and by proxy- I won't list all that), Hebrew, and Aramaic (and by proxy all Indian languages but one, as well as Tibetan, Phags-pa mongol (and by proxy exactly 5 letters of Hangul), Thai, Lao, Sundanese, and Javanese). There's a lot of dead languages that used scripts derived from Egyptian too but I didn't mention them because I'd be here all day listing stuff like Sogdian or Norse Runes.
