Ancient Temples

In looking at the wide overhead shots of the Prometheus' making planetfall, it's obviouse there are mutiple temples lined up. It occurs to me that these are very primitive compared to the technology of the Spacejockeys. Since the star map was found in multiple ancient abandoned sites from Mesopotamia to Mexico on our planet, I wonder if the temples on this alien world were also built by a now extinct race. Perhaps the jockeys built their undergound hangars, and then entered into a dormant state to be reawakened at some point in the future. Local inhabitants may have built the temples over top of them as an homage. Notice that the shape of the temple and the surrounding walls could be primtive reproductions of the horseshoe shaped Space Jockey's craft. Ancient people on our planet built pyramids in the shapes of mountains to honor various dieties, so this seems reasonable.
