As you already know, bungies original plan was for the forerunners to be human. However, they eventually changed their minds and made them an entirely different species. Because of this antagonists in the original trilogy (especially guilty spark) make references to humanity being forerunners. My question is, are quotes like these still considered valid from a lore stand point? What bullshit did 343 come up with to fix bungies mistake? "You are the child of my Makers. Inheritor of all they left behind. You are Forerunner! But this ring... is mine!" "I? I am a monument to all your sins."
