Eh, i don't know if that's entirely possible. The main reason for that is each human was made, really, in a stroke of luck, one personality out of millions, and that all relies on parents being together on the exact night in the same place. Incidents that differ even slightly would most likely result in different children, different ideologies, different wars or lack thereof, and therefore a different present each time.
