How could Hyrule not be on Earth? I mean, there are animals and plants that are only found on Earth, and there are humans. Humans can't be found on planets besides Earth dude. Plus you can see constellations in the night sky that can only be seen from Earth in Hyrule, and the sun rises in the east and sets in the west, like on Earth, because it is on Earth. Also, the Great Sea is on Earth (it's called the Mediterannean Sea nowadays).
You can deny it all you want, but the truth is, Hyrule is on Earth, they even say it in TWW. Sorry dude.
Someday you too will see it as the truth too.
Many works include other planets with the same flora and fauna as Earth, and even the same animals and humans. There are a vast number of reasons to explain something like this.
Additionally, many stories featuring alternate worlds (usually fantasy, as opposed to other planets like in science fiction) use things based on or directly taken from Earth. This can be done for ease, using an already existing ecosystem, for aesthetics or style, such as using things you like the design or look of, or for other reasons. Also, using the same day and night cycle as Earth, including the directions the sun rises and sets in, doesn't prove much. It can be one of the reasons I already stated, but also, just because another planet or dimension is alien doesn't mean it can't happen to function the same or similarly, which could also explain the sun's behavior.
I've also heard the argument of the games featuring the same constellations and such as Earth before, and I've never really taken it seriously. Yes, it could imply that it's Earth, but more likely they're just using an already existing night sky in their own game because it's easy, looks nice, and would be accurate in appearance or design.
Anyway, I'm aware of your stance on these subjects, and I respect it, but please try not to be too pushy about your beliefs.
