It's also a game where there are giants and trolls and elves and dragons and lizardmen and talking cats and etc etc etc
People get nit picky about realism in video games that aren't realistic.
Littledude, even a game has it's own implied logic. Stories have their own logic given. Imagine if a child were told that in The Three Little Pigs, the wolf blew fire instead of simply blowing their houses down. Sure, it's a story and at that point it isn't completely following real world logic, but it has it's own logic and breathing fire is a drastic change from it. Skyrim has it's own logic, and the extreme of a giant throwing the player miles into the air seems to defy it. Do you understand?
