I don't think you guys understand. The question was HOW did the covenant find earth, now how we found out they found earth.
The answer for that is impossible to truly know, because they didn't address it in the books. The most obvious choice is that the covenant attatched one of those star chart mappers to one of the ships either leaving reach or Epsilon system. Or the covenant discovered a nav chart that had the location of earth. Too many possibilities, not enough evidence.
Besides, the books are always blatantly contradicting each other. Notice that in Fall of Reach the star chart from Corte de Azur points to Halo(last chapter with Cortana plotting a course), while in First Strike it points to Reach(The doctor checking secret records right before the destruction of the mountain)? I mean, both books were written by the same guy. HOw could he possibly overlook that?
