I've found another possible piece of evidence in favour of their existence. In the Iliad, it is said that the gods could shapeshift, or at least mask their true appearance. However, they could be recognised by their peculiar way of walking. I've never been able to understand what that meant, since Homer doesn't explain exactly what makes their movements different from ours.
Yesterday I was reading a book and it mentioned the fact that aliens are sometimes reported to have a strange gait, which is described as 'shuffling', 'hips moving strangely', 'sideways'. Could that be what Homer was referring to?
Here are a few pages that mention this detail:

>They walk with a strange shuffle because they aren’t used to the Earth’s gravity.

>Moved like knees permanently bent, instead of walking they more like shuffled and rolled(?) from side to side.

>In the book Missing Time. (3) abductee Steven Kilburn said under hypnosis, when he was describing the gait of one of the Greys, that "when he walked, it was almost like he had two really bad knees. He was hobbling almost… shifting his weight to the left and right….And he drags his feet a little bit…."
>In Matrix II(30) there is also a report suggesting that some Greys have difficulty walking. Paul Bennewitz stated in a letter: "Many in this culture (Grey culture) walk with a limp or shuffle their feet."

>Three subjects described a being’s shuffling motion, not specifying whether this was on or above the floor/ground. And two indicated a “jerky” motion.
