[Having the bottle and the cider there for it couldn't hurt, that's for sure - and he nods in agreement with that notion. That's for later, though. For now he's got to get through his current explanation.]

Well, likely there are. Maybe just not ones folk know about. Anyway, you take a couple of these continents and some bodies of water and maybe some islands and the like and put them all together and you've got a planet. Or a world, if you like. You can use either one..and a space ship will let you travel between planets so you can visit more than one of them. Like if you traveled between continents on a regular ship, only larger. Does that make sense?
