We find an earth-like planet that already contains many life forms. Among them are human beings, in the equivalent of a midieval era. They're the same as us biologically. What would you conclude?
But I would also wonder when aliens took them. Did they take them during the middle ages, or did they take them much earlier, and they just followed a parallel cultural evolution? That might influence my decision on whether the aliens are a threat or not.
One other thing: is the idea of time-traveling humans from the future feasible at all?
