First of all, we know the halos were already activated and set off by the forerunners once before. Now if you can recall back to the first halo game, there is a statement from Cortana saying that Halo's landscapes look very similar to that of Earth's. DING DING DING! That most likely means that the Human forerunners from Earth built the halos as a weapon against the Flood. That's why the Ark is on Earth. The human forerunners built the Ark to destroy the flood but keep at least part of the human race alive. Now the halos destroy everything living organism in the universe. Now the only living beings we know of are the humans, covenent, and the flood. So the humans and covenent must have at least know of each other in the far past because at least a portion of each group must have entered the Ark otherwise there wouldn't have been either covenent or humans left in the halo games. There also must have been some sort of Flood virus that some how entered the Ark to because we also know that there is still Flood virus around. This would also explain how the covenent still know about the Ark and its whereabouts today. For the humans, they must have forgotten over time..........or did they? Well this is my idea of who the forerunners are. If you ask me it all goes together. What are your thoughts?
