Bro, if Eve was a jew, that would make all of humanity jews. But that's not how it works; jews are descended from Juduh, Hebrews are descended from Eber, Semites are descended from Shem, and ashkenazis are mostly descended from edomites and eurasian mystery meat mongrels. Eve predates all of that. Furthermore, most people in the Old Testament are not from the tribe of Juduh and therefore are not jews.
