Well, historically, written mathematics more or less started in Greek.
Yes, there were some mensuration stuff in Egypt, first, but the
characteristically mathematical activity of proving obvious statements
from other even more obvious statements, started in Greece.
Secone, mathematicians have always used a large variety of kinds of
symbols and type faces to systematically distinguish different kinds of
things, a kind of informal static typing that makes their formulas more
visually distinctive and easier to follow.
Greek letters are just part of that.
