Real or fake?
If real, surely the cow would kick or react in some other way, rather than remaining in a grazing position? It would also be an incredible stroke of luck for someone to be in the right place, at the right time, with a camera. And if you saw a cow being beamed up into a space ship, would you just stand there filming? Or would you flee/take cover, just in case you ended up being the next to be beamed aboard?
