Well, ignoring the fact that humanoids have been on Earth for a relatively short amount of the total time the planets been sustaining life, that it's something of a fluke we're in charge at all (thanks to that Meteor/increased volcanic activity/Adric/whatever removed the dinosaurs) and the world isn't ruled by lizzards, that most planets (assuming same size and atmosphere) that could theoretically support life won't actually be all that much like Earth anyway because our evolution depended on circumstances created by our distance from the sun (and it's a very narrow margin for the climate we need, if Mars had ever supported much life it wouldn't have been that Earth like) then the point is valid.
