I, personally, think that the forerunner(s) are some sort of god-like species, who created lots of races through their many tests and experiments. The first time they used the halo(s) must have been like the "flood" in the bible where god destroyed the earth in order to start a fresh. Maybe the forerunner(s) saved some of the races from the destructive force of the halo(s). Then to help them re-establish themselves, they must have given them help with new technologies (hence both humans and covenant having MJOLNIR armor).
