Check out the tiny blond girl in the left hand bottom corner at 3:52 seconds. Have you seen anybody with eyes that big? How is it possible for the
camera to pick up the true features and not the human eye? Can you imagine that real aliens showed up at this news conference what are the odds?
Yeah, well, I see what the OP means. The skull size of that "blond girl" does appear to be much smaller than rest of the audience. And depending on
the lighting, she does look more "grayish" in color.
But out of fairness, "aliens" do NOT, I repeat, do NOT make themselves obviously known - that would be an easy target.
