We didn't know if it still have a 100years or the earth is still alive from that year but if i think on how the world is after a 100 years pass by, i think i'm dead for that years lol. Maybe there is something happen to earth that change for every people who live in the earth. It is posible that another creature is go in the earth and live the same on people. That so exciting if its happen to that 100 years.
