HLN-A Discovery #13

I wonder whether there are no humans anywhere on Earth anymore -- other than you survivors, of course. No sign of them anywhere on my scanners. Earth’s a big place, of course, but you’d think there’d be radio signals or something to let us know we aren’t the last ones on earth. And if there are no more humans, where’d they all go? Did they do each other in, or did the titans get them? With all you humans accomplished, you’d think there’d be a remnant out there somewhere.
