The theory applies only to YMVT, and I have not and will not make a truth claim for an origin story, because there is no recorded history to officially confirm it.
(I should add this as my signature so it's on every post, since this friggen strawman is bound to be asserted again.)

And there it is, immediately following my declaration in bold!
What the actual hell is with these trolls?!
