I don't think that Earth is the original Forerunner homeworld any longer. Also, rather than the Ark being a structure that was built there, I think it was a ship. In the Bible, Noah's Ark carried two of each animal (including humans) to safety. I think that the Ark is a Forerunner ship that landed on Earth to allow the Forerunners to continue to live after Halo was activated. It was most likely programmed to find a suitable planet far away from the rings, and release the DNA that would eventually become humans, and other inhabitants of Earth. Titan AE anyone?
