If you don't read the front page, CUTSCENES! (Destiny)

Was this explained somewhere? I haven't really been excited for destiny til I finally got to play it yesterday :D so I haven't been really following post's or lore.

Well this is what I've surmised from the cutscenes, the Grimoire cards and what Bungie has said about the game in the past. Some things just 'are' in the world and they don't try and explain them (at least not so far, and hopefully never) - "The Traveler's Light" just is. Like 'The Force' was in Star Wars pre-midichlorians.

So, humans have some sort of eternal 'soul' separate from their body - which is how the Guardians can come back initially and again each time they die. But that resurrection isn't free or easy to accomplish. Therefore only some dead humans come back as Guardians. Some Guardians do die permanently as well (again) - as evidenced by the dead Ghosts lying around and the incomplete Guardian missions you pick up during the Story. Souls are probably what separates the Exo from other robots we see in the Tower, I bet.

Fallen seem to have 'souls' in some sense as well: you can see them 'screaming out of their bodies' when you score a headshot (to use Bungie's description). Your commander on the Devil's Lair Strike mentions that you should 'send their souls screaming back to hell.' Literally or figuratively I don't know, but the idea of a soul certainly has great currency in the world of Destiny.
