So, who sealed up the tunnel where the "ghosts" were hibernating?
(I really thought the "hieroglyphics" were going to turn out to be a warning from some other species that had sealed up the "ghosts.")
Why would they care about other entities on their planet when they obviously weren't using it themselves. There was also no evidence of any kind of civilization.
