Well to look at The Awoken u must look at The Hive, The Vex, Exo, Humans, Cabal & Fallen, truth is we don't know if humanity had other alien species - it's possible their were other alien race, or The Travelers/The Darkness appearance caused new forms of life to form on the multiple planets or if they're all humans just changed. It's extremely confusing due to this it is really hard to say/pin down something especially since the length of The Golden Age is unknown. The Hive know the darkness well to be in regular contact with it for a long time but how long? If they are all from beyond our system why are other planets beyond our system not mentioned? Did The Traveler &/or The Darkness bring them all or did they come themselves? If so, how? Did they all just form on other planets in our system? Then theirs The Vex who I believe are simply bad Exo's that opposed the good Exo's we play as & that The Vex are from the past during the war with The Darkness, which means my theory would opposes the theory that the Exo's are human souls put inside machines to fight The Darkness. That might would mean NONE of the other races - Hive, Vex, Awoken, Fallen, Exo & Cabal are changed humans. The Fallen &/or Cabal don't like The Hive or Darkness but they also don't like The Guardians. That means they have a grudge against us because they were a race lost to the darkness or they consider it just business & think it's a better bet to side with The Darkness or both. It is also unknown if Awoken are immortal (immortal & invincible are 2 very different things mind you) if they are then that would explain a lot. They are obviously a old & very wise race also they don't go around saying they're humans that have been awoken by some event nor are maintaining a human like culture, they seem to be they're own thing. Yes i'd expect them to have they're own culture but it is FAR different from human cultures, no roots seem to go back to human cultures except for the shop keepers whom you interact with however it clearly states earth born awoken are not the same as "pure" reef born Awoken which means they might not be changed humans either but I could be wrong as human culture is massively diverse but I still always notice similarities. It gets more confusing if u try to say humans were "The Last Cycle" & we are entering "A New Cycle" like it went from dinosaurs to humans.... The only things we can draw is that they might be awoken humans, awoken by what is unknown perhaps even to themselves like The Exo. We know The Travler & maybe The Darkness can create life, the most direct solid example is your ghost. Are they aliens or new formed life, unknown however we know they are old, wise, elfish, vampric race & desire to be left be which may mean they do not like fighting much or do not concern themselves with the world of mortals, earth, much
