Statues?

I'm not sure if anyone has noticed but on the trailer at this website, if you jump to 59 seconds, as the Alien vessel is rolling and tearing apart, and there are two humans running from the in falling wreckage. Pause at 59 seconds. Look at the rock to the uttermost left in the middle of the screen. I'm sure I'm not seeing things but it's statue of several heads stacked on each other. One almost looks like an eagle. One can speculate a lot from this. If I'm wrong, sorry. If this has already been stated please remove post. Are their several planets on this film? Maybe even different time lines. Maybe one of the planets is planetary tomb.
