I think the riddle shouldnt be read: 'Nothing has outlived the gods', but I read it as:
If the Gods die, Nothing will remain.
This follows nicely on the story for GoD, (tributemasters introduced because the gods are turning away from the races) where if we keep killing the gods eventually the world will end and nothing will remain, or maybe just chaos and order forever in opposition.
I do still think that the second sentence is weird, there cannot be more or less of nothing imho
