100,000 years ago, early humans existed and were migrating off of the separating single-continent Pangea.
Hm.the Index must have an important role. It is commonly believed that the Index contains mapped DNA genomes of life forms throughout the galaxy. No, in fact, not common belief. It was practically said by Bungie(the definition in the banner of The Library) To activate Halo, one would need the Index. Thus, it is possible that the Index reseeds the galaxy of life. Of course there were survivors after the last activation of Halo. Since Halo was never really activated in both games(although I think it will be inevitably), the true function of the Index is never known other than that it is the key to Halo.
