BACK WITH MORE QUESTIONS what is "linear b"? I figure it's a language obviously, but what?

The first Greek tribe/civilization to use letters was the Minoan one. Their alphabet was called Linear A and it's not yet deciphered.

The Myceneans that came after the Minoans, had Linear B. Which was deciphered and it's how we know that the Olympians were a much much older religion that most people thought at first✨

This is Linear B

(The day we decipher Linear A I'll cry happy tears I stg, it's killing me that we can't read those texts!!)
