You don't debate Merari you simply take forum posts from former employees and assume everything he writes must be true. (unlke the in-game lore which often contradicts its self)
A big deal is made out of the religion of the nine divines but according to some lore the original eight divines religion was a compromise by Alessia merging the Nordic and Elven pantheons at the end of the first era. What happened to those missing Elven and Nordic gods? Despite the years the Amulet of Kings remained lost in the second era and all the times the throne sat empty the issue with the Oblivion crisis didn't occur until Uriel Septims death.
The in-game lore is already contradictory, bias and full of holes. Just like real history books. So I have trouble assigned an article to the Thalmor when it was written before Skyrim as made but not included in the game. I don't trust the lore in-game at face value, I certainly won't give what was left out a higher level of trust.
Like with Earth history, what is most likely closest to the truth can be teased out by putting slightly differing versions of events next to each other and see where they coincide.
These elven and Nordic gods are not missing, youre thinking about it the wrong way.
Imagine a huge circular dark room with a lit shape on a pedestal in the centre. You are at the rim of this room. From where you stand you see the shape and it looks like a triangle. You move across the rim to stand somewhere else in the room and look at the shape, it looks like a square now.
You move
towards the centre of the room and see the shape up close for the first time. It is not a triangle nor a square, but a shape that looks like either when viewed from a specific angle.
These are the gods.
Those old gods still exist, they are just seen in a different shape now. They are the same concepts, the same Aedra, but different aspects of them are now at the forefront.
This process is called
mythopoesis where belief shapes reality.
What the Selectives achieved when they danced on that Tower, aside from the middle-dawn, was the creation of Akatosh, who before had not existed, as such. After the middle-dawn he always had.
This does not mean that Auri-El suddenly is no more, for the merish races he is still the most important ancestor.
They are standing at another point on the rim of this circular room.
Six are the formulas to heaven by violence, one that you have learned by studying these words.
The Father is a machine and the mouth of a machine. His only mystery is an invitation to elaborate further.

The Son is myself, Vehk, and I am unto three, six, nine, and the rest that come after, glorious and sympathetic, without borders, utmost in the perfections of this world and the others, sword and symbol, pale like gold.

Below me is the savage, which we needed to remove ourselves from the Altmer.
Above me is a challenge, which bathes itself in fire and the essence of a god.
Through me you are desired, unlike the prophets that have borne your name before.

Boethiah and Azura are the principles of the universal plot, which is begetting, which is creation, and Mephala makes of it an art form.
For by the sword I mean the first night.
For by the word I mean the dead.
