Question of The Space Jockey as a suit

Empty Space Jockey like suits of the engineers found standing either side of a tunnel leading towards the space jockey chamber in the Juggernaut.

Below, Images from the movie Fire In The Sky (1993), directed by Robert Lieberman which is based on the Travis Walton alien abduction case, here the character Travis Walton wakes up in a space craft and curiously encounters space suits of extra terrestrials floating around inside a zero gravity environment, presumably the inside of a space craft. It suggests that all the witness reports of what are known to be "Greys" may not be all that they seem, maybe they are suits and something else is inside them.
