Before you make any more of an arrogancy-induced idiot of yourself on that thread- you still don't get the question. If Link is sent back in time, the timeline splits- Adult Link is sent back and the AT continues WITHOUT Link or his descendents explaining why the world was flooded for
tWW. The CT continues with Young Link not opening the Sacred Realm. The question was 'What if he wasn't sent back'- basically- what if the timeline wasn't split and Link was allowed to carry on in one timeline providing descendents to stop Ganon in
tWW's backstory.
And people won't take kindly to being called 'amateur' by someone who hasn't even understood the question!
