We could invent all sorts of details of the lives of the castaways, based on these pictures. What is the big pit in front of the container row, for example? A former pond? A former charcoal pile site? Did something explode there when the supermen fought each other for the last remaining piece of bread?
And what were all the supermen doing outside when our heroes arrived? Visiting the local well? What else of importance is there on this planet? If dozens of humans and an entire species of ear-burying critters look like mere lichen on a starship's scanners, aren't the odds that something else of note survives as well, hidden by the sandstorm static and whatnot?
