Do any of you know for a fact that the writings that bear the name of a particular ECF were actually written by that person? No, you don't. You just take the word of your church on it. For all you know, every writing of an ECF could be a forgery.

You could say the same thing about any of the books of the Bible. The Tradition of the Catholic Church tells us who wrote them, and you accept that tradition.
