I have a hard time believing any of these "alien videos" (alien autopsy, alien interview, etc). Primarily because these "aliens" are always humaniod. If these things are supposed to be life forms that evolved on another planet in another solar system many light years away, why do they have two eyes, a nose, a mouth, two arms, two legs, and a body structure that matches our own so closely? The course of evolution on our planet alone has created an amazing diversity of life (and this life all descended from a common ancestor!).
I guess the "ancient astronauts" theory might explain this, but I don't put much stock in that either. I guess I'm a skeptic.
Still, the videos always manage to genuinely creep me out.
