Usually when an atheist says "there is no god" what they mean is "there is no reason to take seriously the claim that there is a god, because there is too little evidence". And by "too little" they mean the same amount as there is for the core of the moon being cheese, or something, i.e. essentially zero. So I don't think they're really making the assertion, or the mistake, that you think they are.
