this is my theory, i have posted it several times before, they forerunners built the halos to stop the flood, they flood escaped and the forerunners set the halos off, killing all the smart life, only like a few survied, i say 2 and they went to earth to live, thus having to start over cuz they forgot how to do the technology and what not, and just lost it over the slow decay of time, and the forerunners had to start over and became humans
