I don't think it's a fallacy; giving a single statement can't really involve faulty reasoning (in and of itself). I could say "Unicorns live on the moon", and that wouldn't be fallacious, with or without reasoning or evidence (ignoring "vacuous truth"). It's just that no one will probably believe me.
