first off: MC is definately not a forerunner,as you guys have already said, and neither is any other human. If you have read the books you should know that without a doubt.
Also, I doubt that the forerunners had any previous association with Earth's current inhabitants (humans, present day animals,etc.). They MIGHT have put an artifact on/in Earth 100,000 years ago, but they certainly never met any humans. As for the symbols engraved on the granite from Sigma Octanis IV, I believe those symbols were engraved into the stone by the forerunners to point the Covenant, or anyone else, to the artifacts, one of which being Halo.
