As anticipated internal organs reflect extra-terrestrial origin: overall complexity precludes classification and identification. Notably, the central nervous system [analogous] was characterized by multiple nodes networked throughout the body, extreme density of cerebral matter, various unknown ganglia, all connecting through a rigid head [analogous] lacking notable sensory organs.The creature's external and structural anatomy suggesting a level of development far exceeding our own, all while retaining a troubling similarity to human physiology.All findings are speculative. Despite structural similarities to human anatomy, the creature's nervous system is of such unusual composition that it's unlikely that we will be able to comprehend its functions, much less the creature's motivations.Accompanying the creature were three segmented spheres of unknown composition that orbited the specimen before its death. These have so far resisted any attempts at tampering, damage, or even chemical sampling. All three objects stopped their motions at the exact moment of the creature's death. They currently appear for all intents and purposes inert. Despite this, they are being kept in separate level 4 security vaults under 24 hour surveillance and heavy guard.___________________________________________________________________Why should a creature of such baffling complexity and distinction reflect human physiology? Is this being an emissary? A distant cousin? An astonishing example of parallel evolution?[Addendum]-Many initial witnesses report a feeling of deep unease and dread when confronted by the creature [above and beyond what might be expected by suddenly encountering an alien]. Several more specifically report not being disturbed by the specimen itself, but rather were struck suddenly with a terrible certainty that it merely preceded something about which all sentient life on Earth should be deeply and immediately concerned.Was it attempting to warn us? Or to threaten us?
