Have you ever noticed that doctors handwriting seems more like a drawing? I swear they have some secret visual language that anyone without a medical degree is oblivious to. Doctors do the same shit as aliens anyway, right? "Help" people by cutting into them and stitching them up. Who's to say something interstellar isn't really going on. But, then again, they could just be smart people in scrubs, or as I like to call them, "brain robes."
