Well, I felt that since there were seven worlds in the system, there shouldn't be more than 7-14 different species present (since a world would usually only harbor 1-2 different sentient species). The number of species present in the stadium vastly exceeded the number. Even though the Doctor and Clara were implied to not supposed to be there (or at least that was how I interpreted that line), there could have just as easily been other species there.

I'm not as worried about calling them all natives to the system as when I originally posted the thread though. Still not certain, but I don't think it is an unreasonable speculation.
