NEW: Ex-CIA & Pentagon officials describe "four alien species" that pop up as the first google image result for "types of aliens"

@uncle_deluge It would be so funny if the cheesy 1960s scifi alien designs turned out to be the ones that got it right

@Joominmames @uncle_deluge I wouldn’t be too surprised if aliens from an earthlike planet convergently evolved a humanoid body plan. Four ancestral legs, two of which evolved into graspers. Sensory organs clustered around the brain in a protective case at the front/top of the body.
