You know, I don't think the Covenant found all the Halos, if not even one before the Pillar of Autumn. The Prophets kept reassuring themselves that more rings would be found after the debacle at Halo 04, and the Prophet of Supposition noted that the discovery of Halo was the greatest bestowment of their faith in over a millennia. If the Covenant hasn't found the Halos...well..we know the remains on Halo get more revealing with each game.
Why only Africa? Why not ancient Egyptian relics, or central American ruins? There's some pretty bizarre stuff at those places. Like how the pyramids are aligned directly with a star, central American pictoglyphs that depict a chariot-like "spaceship" sphere(you'd think it's something of Forerunner design), and so forth.
