Transmission theory: what the heck was Tolkien thinking?

[gondowe]

We don´t know what Tolkien could have devised as the "Real transmission theory", but with the data we have the transmission posted by me above is the more plausible theory with its weaks, in my opinion.
In other way, a text like the Awakening of the Quendi never was though, in my opinion again, as a "real history tale" within the Mythology. It was said that it was "Actually written (in style and simple notions) to be a surviving elvish fairy-tale or child's tale, mingled with counting-lore" .
Of course this is indepently of the fact that Elves knew the "Truth" and Men don't.
