However, there is NO POSSIBLE WAY to get around the fact that for Rinoa to be Ultimecia, Rinoa had to have been able to outlive a normal human being, which Squaresoft disproves.

If Ultimecia lives too far into the future for Rinoa to naturally become Ultimecia, then Rinoa is not Ultimecia, QED. End of discussion.
Thus, why I obviously don't own a copy of the official squaresoft document. But I do own a copy of FF8. And in the game FF8 it's vague.
