See, now there's a problem with this. If they made the big bang which made us, what made them? Ahhhhh, now we see that this creates more questions than it answers.
Yes, According to the Storyline of Halo, Humans descended from the Forerunners or looked similar. The Monitors of the instalations, specifically 343 Gulity Spark of Halo instalation 3, claimed you were the "reclaimer" which, most likely was used for when a Forerunner was present.
Hmmm... if the halo universe was real, then it would stop all the arguments and wars fought over religion, and who is right and who is wrong. Then again, if the halo universe was the real one, in about five hundred years life would suck really bad for mankind...
Lol, perfection. I think that would be cool, but unlikely. Why? Because I was there. Yup. Tex, Nemi, TDF, Sargeant Sarcasm, I'm sorry, but I'm revealing the truth. You are all God, in disguise. I knew it from when I joined. I am from 20 years in the future. I travelled back in time to witness the event, and when I returned my machine broke. So I'm stuck in this time. It's not bad, it's a forgehub user that inspires griffball to become a real sport. Anyway, it was sort of like you described, only the forerunners were the Sarcasiams. And the Texans, Nemiharans, and Truedarkfusians banded together to reset the world more perfect. And you became god. Nice try though.
