I mean there's Jun, Gray Team (i think it's the team marked as MIA), and there's a little possibility that Noble Six may have survived, there isn't any proof that Master Chief is the last spartan alive, so why do humans think he is?
Right, but you've forgotten a veeery important fact: Master Chief is a SPARTAN-II, whereas Jun & co(not George, but he's dead anyway) are SPARTAN-III's. To put it simply, all the other SPARTAN-II's are supposedly deceased or MIA, which leaves John 117 as the last 'true' spartan, a SPARTAN-II, even though he is now MIA too after halo 3.... :)
