You can believe all you want of what is canon or what is not canon in TES mythos but your living in a delusion if you decide that something is real just because you like it. Just because you believe it, canon is actually quantifiable and able to be judged. If the lore was whatever someone made it in their mind, then there is no lore because there is no point of reference. This is why lore belongs in the hands of the few, lore writers instead of the masses. Just because a lot of people believe something to be true doesn't make it so, it's the architects of said mythos that decides if something is true.
I think the whole teneur of the last few pages edges inescapably towards that thing wich I stated a few times before in varying ways.
Its the majority that decides whats science/canon/lore/mythology/theology.
What is a fact changes, and a viewpoint changes, but a definition does not. It just gets tweaked with more knowledge. (so.. a banana can also be red..)
In the end, it boils down to concensus.
Your viewpoint, while perfectly valid and interesting, is a viewpoint unsupported.
I have stated before, you may be right, and if you eventually prove to be I personally will prostate myself upon your carven image and exclaim: I am wrong and you are not.
In the meanwhile, if only for sake of not adding to the confusion, it would help if we all accepted the same fundamentals.
There really is nothing to gain from pointing at accepted lore and saying its not lore. Not unless you are von Daniken, or actually have some quantifiable proof.
For the sake of mediocracy we need to have some sort of common ground, from wich we then can deviate.
There is no point in deviating too early, lest one ends up questioning the colour of the sky.
We need to start not from personal knowledge or preference, as that is inherently biased, but rather from what we all know and is constant.
I think the monomyth is a good starting point.
