Anyway, I'm not sure where your going with that. Then and now, the Seal War says Ganon went in, wished on the Triforce, and was sealed. I've given evidence that the story is still the same today. OoT is not the SW anymore. Even if we were talking like it was 1998, your number 2 has no evidence. That is speculation. VC's description of LoZ says that Ganon has escaped the Dark World, but that doesn't automatically connect it to ALttP or the SW. There is also no evidence for a new Ganondorf being born. FSA somewhat implies it, but its never been stated anywhere and someone could just as well say that it has never happened. Your number 5 doesn't make much sense because your acting like the Seal on the Dark World is not a seal at all. If it is "sealed", nothing comes in and nothing goes out. That doesn't mean that Ganon can mysteriously escape without finding a way around the seal. And even if he did find some other way out, and LoZ took place before ALttP, then why would he need Agahnim to get him back out? Why wouldn't he just use whatever means he did before to escape? See the problem with that?
Ganondorf "rediscovered" the Sacred Realm because at the time, no one knew where it was. During OoT, people knew where it was. So prior to ALttP, generations before, people knew where the SR was and how to get to it (certain people). By the time of the SW, everyone had forgotten how to get there. Ganondorf was the one to rediscover an entrance. That is what that whole thing means. He found it, went in, wished on the Triforce, evil creatures started coming out, so it was sealed up. Ganon couldn't find his way out so he got sealed in there. Then we come to ALttP.
That is pretty clearly what the games, even today, describe, based on my in-game evidence, descriptions, and quotes.
