Years ago I read an odd short story that stuck with me about aliens discovering that humans were "made out of meat" and deciding that news was "just to strange" to report back to thier home world and then decided to "forget the whole thing". Presumably the aliens were an ethereal form of energy or a sort of non corporeal life form capable of assuming human like form to discuss the entire event. For some odd reason this story has stuck with me for all this time. Obviously it stuck with some else since I have found a video based on the story on youtube:
