Showcase #202:"The Destroyer"

It's the year 2057 and Mars Flight XT-108 is returning to Earth after three and a half years. There's just one problem: They've lost all radio contact with the Earth. What has happened while they've been away? Has Humanity forgotten them? Has everyone simply checked out? Or have the inhabitants of Earth all gone the way of the Dodo? Is there anyone left on the planet who can answer their questions? What if they are all that's left of the Human Race? If that is the case, how will they react, and what will they do now?
