His existence was dependent on the people who needed him, just like every other Primal.
Thus doesn't outright jeopardise the validity of my theory.

While I don't believe they need worship to MAINTAIN a physical form once summoned, I still think Eikons need to be intentionally summoned the first time in order to obtain a physical form.

After they have that physical form though, only their destruction causes them to lose it. Where as primals can actually burn themselves out and dissipate simply by using more aether than they take. (That being a possible explanation on why ifrit doesn't just march to Ul'dah's gates and temper everything in sight)

So even if Sephirot's form that Allag faced was summoned some 5000 years past, since they were unable to actually kill it and the other triad ny theory, if correct, means that by the eikon's will alone it can exist where as a primal requires a continuous supply of worship in order to not fall apart.

And it may simply turn out that their ability to do so may be nothing more than being able to absorb all 6 forms of elemental aether instead of just one or two and by extension be able to leech off the mother crysta's aether as their sole source of energy where as primals only seem to drain one or two at most (With Bahamut and Phoenix as possible exceptions) thus making the power of an Eikon greater than a primal on the most basic level.
