Occam's Razor, when stated in that way, is a logical fallacy. It is almost never the simplest solution, no matter the subject being looked at. And even when stated correctly, it's wrong at least 60% of the time unless it is amended to include "of the solutions supported by evidence and repeated testing." And even then, it's wrong often enough that entire branches of science no longer use it. I really wish people would stop using that as if it somehow supports their argument rather than suggesting their argument is inherently wrong on some fundamental level and thus should be discarded outright as unworthy of even the most basic consideration.
Besides, if you go by what Aonuma is saying as of late, BotW is up to us as to where to place it. Until he changes his mind, he's ceded control over BotW's portion of the timeline and how we arrived there to the players themselves. So, technically, any placement at all is officially unsupported.
But, if you want to continue, shall we take this to another thread? We've derailed this one pretty hard.
