I was replying to your original post, which said nothing about mathematics. Rather it was about knowledge: "There is no such thing as knowledge that has never even been written down a single time by anyone or anything." And there's no evidence one way or the other about pre-writing math knowledge.
And of course Chinese is not written alphabetically, although I'm not clear what your point is about "full alphabets." (Technically, Arabic is not written with an alphabet either, but rather with an abjad--and the Arabs invented algebra. Similarly for most other languages written with Arabic script. But I won't argue that point, which I admit is rather esoteric.)
