You know all those early proto-humans you see in museums (except the Creation "museum") or read about in books: Homo Habilis, Homo Rudolfensis and the like. Did they have their own heaven and hell or are we sharing it with them or is there just one species of Hominid in heaven and hell, namely our species, Homo Erectus?

If there is just us, at what point in our evolution did we suddenly become eligible for eternal life/damnation? Given that you can't do heaven and hell by halves, there must surely be an exact date where all this started to happen. At what point in time did heaven and hell open for business?
Mea Culpa! The person that corrected me on species name is completely correct. Homo Erectus is extinct.
