What I'm saying is that if there wasn't a seal, then the whole cinematic was a representation of the massive release of aether into the world and the birth of many primals. The ambient aether in Eorzea before the explosion wasn't nearly enough for the Primals of the world to exist as easily as they do today. Secondly, those Primals that come flying out of the explosion couldn't have been sealed away, because, as we know, they are not Elder Primals and Elder Primals have to exist for 3 or more Astral Eras, since elder-ness is a measure of age, and not power.
