Uh. Yes? There was human life 500 years ago in our world, wasn't there?
In the future, chocobos have taken over the universe and humans are left to sponge in chocobos fecal matter as they watch in awe as the chocobos fornicate relentlessly as a tribute to the great Leader of the Chocobos, Spingsker McDickerson, who is 501 years old and has lead the Chocobos into a new era of sodomy en mass upon the unforgiveable human species. So yes there is human life 500 years from now.
