Author statements and such secondary canon statements are valid only if they are supported or mentioned in the verse.
The statement of higher existence and the inability of 4-dimensional beings to can't interact with Athena, as well as transcending infinite 4D universes and evolving to a higher plane of existence, are contexts that show that higher existence is actually higher-dimensional existence, and these are supported by achievements in the verse. In short, if the statements contradict in the verse, we do not accept them.
Let's see what the author means when he says "higher existence" and "higher plane".
Cory Barlog calls the realm Athena ascends to the "higher plane of existence" and is a higher dimensional plane of existence with these extra contexts.
And when Athena ascended into this realm, her spiritual, mental, and physical existence, in short, her entire dimensional existence, was elevated to the same level as this higher dimensional plane/realm.
This was the reason Athena was corrupt. When Athena evolves into higher existence, she expresses that she sees all reality and has all the power in this realm thanks to UES. This is another reason for Athena's corruption.
The statement "power and existence that transcends all beings in the Greek realm" and "higher existence" were not distinguished by Cory Barlog, on the contrary, Barlog states that the reason for this is Athena's ascending to the higher plane of existence, in short, higher-dimensional existence, and that is why she degenerates.
Also, given Mori's case, the only context was that he simply evolved to the intersection of space-time, we don't see the consequences of equating existence there like Athena, or we can't see any more context behind it. This is exactly what Mori lacks.
Kratos is deceived by Athena's appearance and tells her that she looks like an Olympian, but Athena expresses that the view of her deceptive by her very existence. Also, a higher dimensional being may be human sized, which doesn't mean it doesn't have an extra axis.
We also see higher existence in the comic, this time depicted as a space that encompasses all of Egypt and beyond.
Edit: The reason why the realm is higher dimensional is that the phrase "higher plane of existence" actually transcends the infinite 4D realms and the mind, soul and body,4 dimensional beings cannot perceive and reach this realm, which is a higher plane of existence.
And Athena, after ascending to this realm, transcended all beings in the lower plane and infinite 4-D worlds like
"higher existence", and ascended to the plane of existence that they cannot reach and reason with, and her power has accordingly increased both from the higher dimensional realm and because of her existence. Because of UES bullshit.
To explain the UES, of a character in GoW has a 5 dimensional existence or is powered by the 5 dimensional realm, their mental, spiritual, magical and physical power will scale fully into this realm.
Also, Kratos has no trouble interacting with beings that have a 4-dimensional existence, but he can never interact with the ascended Athena in pre-hope form.
To sum it all up ;
- The statement "higher plane of existence" in the series is actually a realm that completely transcends lower planes and infinite 4D structures as well as 4D beings, making interaction and perception impossible. No being and power on the lower plane (including 4-D beings) can't sense, interact or access this realm.
- When Athena ascended here, not only did her existence ascend to this plane, but her power also scaled to this realm thanks to the UES, because it was here that she gained her power and equated her completely existence with here.
- In Fiction, you can have a higher dimensional existence, in short, have an additional axis and be human-sized.(like a 4 dimensional cube the size of a standard cube...)
However, despite this, this confusion is cleared up in the verse and
states that the appearance of Athena is a deception according to existence.
- The higher existence we see in the comic spans the entire Egypt realm and is completely beyond it. This is another proof of a higher dimensional plane of existence.
A small addition to encompass not the entire egyptian realm, also all the mythologies and realms found in GoW, plus a higher existence that completely transcends them.
I guess you don't know, but everything you've said has been discussed over at least 2 or 3 revisions, and people knowledgeable about Tier 1 have confirmed the existence of higher existence and Athena.
It's not the statement that matters, it's the context behind it and the feats that support them. And GoW has a lot of them.
I would also like to point out that for a verse to take a geometrical scale, mathematical expressions are not always needed because it's context and feats that matter.
Or, there is no need for statement like "uncountable infinite superiority" directly, as I explained above, there is an ontological superiority for higher existence. That's enough, we have never and will never scale with "direct" statements, always looking at the context and feats behind it.
Also, a space with a higher spatial dimension is already ontologically, i.e., qualitatively superior to the lower plane, someone who has a scale to it qualifies for Low 1-C or Tier 1.
@ImmortalDread First of all, I didn't mean to make this comment specifically against you, but I apologize if there is any misunderstanding and I now present my arguments to the OP in general
