Far out in the uncharted backwaters of the unfashionable end of the
Western Spiral arm of the Galaxy lies a small unregarded yellow sun.
Orbiting this at a distance of roughly ninety-eight million miles is an
utterly insignificant little blue-green planet whose ape-descended life
forms are so amazingly primitive that they still think digital watches
are a pretty neat idea ...
