I’m pretty sure these alphabets cover almost the entire globe

Also descended from Egyptian. Forgot to add them though. They’re the link between Egyptian and Greek. and Egyptian and Aramaic

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.
