But the character does not exist. They are imagined by all the players as being in a specific setting and doing specific things only because they are narrated to be doing so (and the clue there is in the word we use).You as a player don't cast spells or use weaponry but the character you are playing the role of probably will. You ARE your character as far as the game world is concerned.
It's true that it is possible to imagine a character doing stuff in an alien world without narrating it, but it is not possible for the fiction thus imagined to be shared without that narration. And building a shared fiction over which all players have some degree of authorial control (even if it is very strictly limited to "their" character's actions) is as close to a definition of roleplaying as I have come accross.
