Prometheus: The 'Space Jockey As A Suit' question

Leading from

Prometheus afterthoughts
and
Alien: The end of the line and back to the distant past

a) Realising that the space jockey is a suit
Over time, the idea of creatures disguised within the skin other life forms evolved through cinema
and somewhere in the 1990s it got into Ridley Scott's mind that the space jockey could be a suit with something else inside. 

See: Prometheus: Aliens in suits that look like aliens

b) Ancient Aliens in Tintin
The presence of suits or statues along a spaceship hallway and a giant head in Pometheus appeared to be like elements from "The Adventures of Tintin and the Flight 714" which was a story that borrowed ideas from the ancient alien theory that was showing its head around the 1970s. However there wouldn't be any doubt that the statues were merely statues, but the endless questions about them being statues of extra-terrestrial visitors from an advanced spacefaring culture would not go away. Often they would be perceived to be perhaps somehow human relatives of our own who have interbred with humans on earth and perhaps even seeded life on Earth.

c)  Cat people's human body in a cat corpse
Paul Schrader's Cat people remake presented the remains of a human body when a were-panther is cut open.

See Cat People (1982) 

d) The Thing presented an alien life form replicating the forms of other life forms and hiding within these recognisable life forms, that crashed its spaceship on Planet Earth in ancient times.    
See: The Thing (1982) (Still to come)

e) The reptilian visitors disguised as humans in V.

See: V's Visitors with reptilian faces behind human masks (1983)

f) Cocoon revealed glowing extra-terrestrials disguise as humans.  

See: Cocoon (1985)

g) The visitors from "Communion"
The visitors from "Communion" who appeared to be the large triangular face with large slanting black almond eyes contained revealed another life form beneath with a dark face and a snout.  

See: Communion (1989)

h) Mondoshawan suit concepts
Patrice Garcia drew a spacefaring humanoid extra-terrestrial wearing a space jockey like suit. 

See: Patrice Garcia's  concept for a Mondoshawan from Luc Besson's The Fifth Element (1992)

i) "Fire in the Sky" alien suits
"Fire in the Sky" decided to make these outer bodies of aliens to be hard space suits for the creatures with another alien being inside who could discard the suit.  

See: Just like "Fire in the Sky" (1993)

j)  ID4 biomechanoid suits
The alien beings in "Independence Day" were presented a biomechanoid aliens with smaller grey like alien life forms wearing these outerbodies as suits.

See: Biomechanical suits from Independence Day (1996)

k) Prometheus' engineer flight suits
In Prometheus (2012) we find Alien suits standing in the corridor of the Juggernaut ship, that echoed both "The Adventures of Tintin and the Flight 714" and also Fire In he Sky
