Bill gates on Halo: Combat evolved "Halo is the future"
"You are the child of my makers, you ARE Forerunner"- 343 guilty spark.
In a halo 2 storyboard, the arbiter discovers a forerunner coffin. He opens it up, and inside is a skeleton of a regular human being.
Halo legends is a canon anthology series, and in one episode, a sort of prelude to Halo 3 ODST. In this episode, on a far away planet, ruins where discovered. It's freaking scientists out because thd ruins had distinct Indian, Japanese, and Greco-Roman aesthetic elements, (and many more) which asks the question, who the fuck made it?
It was implied this would be one of many keys planted that would lead to more halo media and a great secret being unlocked, that is before bungie left and 343 industries fucked everything up.
In short, in our very own timeline, after endless wars humanity fled to the stars, unlocking the secrets of the human body via the super soldier program, humanity both evolved naturally, and genetically engineered themselves to adapt to whatever planets they found, becoming aliens you see in game. Eventually one of them ascended, becoming god itself. (the great sin) Something happened along the way to piss it off, so it became the flood to wipe away it's mistake. The forerunners captured all species DNA to recreate everything incase something happened, and it did, leading to the halo array to wipe all traces of the flood from the galaxy. This is an endless cycle happening over and over, leading to the halo games.
