Incorrect. Nirn could easily be more different from Earth. Does gravity not work just as it does on Earth? If water flows off a cliff does it not fall? Plus there are familiar animals and plants.
Do what?
Says what?
Again, according to what?
- The moons are the body of a dead god.
As I have said elsewhere, you seem to be simply reading a book in-game and taking everything it says as the literal fact. You can't do this, especially since there are books that contradict each other.
And this is what fantasy is. Science Fiction is something else entirely, both genres can take place on recognizable worlds like our own, and both can be set in completely different ones.
I have a bookcase full of excellent examples, from Asimov to Zindell.
And I'm just saying, as a matter of genre, fantasy is normally based in a world much like ours - at least, ours in the past - with the addition of fantastic things like magic and fantastic creatures, usually creatures taken from real-world myths and legends, like trolls and dragons and vampires. Any story that attempts to be creative with no link to mythology or legend from the real world has pretty much parted ways with the fantasy genre, and has moved into something like science fiction.
