So if anything, The Twelve created the Primals, going by the above.
While I doubt it is the case, you have to remember, this is all belief in world; lore and mythology. It's entirely possible that what is taught about the 12 is a complete fabrication. That being said, in principle I agree with you, usually lore in Final Fantasy games is set in stone and taken at face value.

Cait Sith is an interesting theory, though I would feel like that was a cop out. Odin and Alexander both have some interesting potential as well. As for Odin being battle content, it would not be the first time in a Final Fantasy game where the characters found themselves used and pitted against their previous benefactors.
