*Spoiler*
In First Strike, after the Fred, Kelly, Will, Issac, Vinh, and Dr. Halsey blow up the ONI complex, they travel through the undergound, abandoned mine shaft. Fred is getting his hand's armor upgraded by Dr. Halsey and is running his bare hand over the odd symbols he finds in the underground shaft. (We know them as the Forerunner symbols.) His hand is pricked by the symbol and blood comes out and all of a sudden a huge shaft opens which leads to a Forerunner artifact.
My Theory:
The symbol was taken a blood sample from Fred when it pricked his hand to see if he was part of the Forerunner race. When it analysized it and found it to be a Forerunner's blood, it opened the shaft to the artifact. (Sort of a security procedure.) This proves that the Human's blood is the same type as the Forerunner's blood which means the Humans are the Forerunner!!!!!
Thank you for your time.
