Here's my Forerunner theory. Tell me what you think.
Despite the efforts of MC and the UNSC, the Humans are defeated by the Covenant. The small groups of Humans that still survive begin a guerrilla war against their alien usurpers. Hundreds of years later, the Humans decide that the only way to defeat the Covenant is to destroy them in the early stages of their evolution. So they travel back in time. They arrive in the distant past, before the Covies have even begun to evolve. They build a civilization, achieving a level of technology equal to that of the Forerunner. In fact, it is Forerunner. The Humans/Forerunner are confronted by the Flood. They devote all their energy to the study of the Flood, in an attempt to find a cure. They build the Halos to serve this purpose. In a last attempt to rid the galaxy of the Flood, the Humans/Forerunner set off the Halos, destroying themselves in the process. Only a handful of Humans survived, on the planet Earth. They fall back to stone age technology and soon forget the empire that they once posessed.
In the wake of this destruction, a number of alien species begin to evolve. These species would eventually form the Covenant. Thousands of years later, the Covenant begin a war against the Humans, starting the circle over again.
