"Gold is a pretty metal, soft and easy to work with for artists and with some interesting electrical properties, but otherwise rather useless other than as a symbol of wealth and power. If an alien race wanted to conquer the Earth (although one has to wonder what there could possibly be here on Earth worth the trouble) all they would have to do is start handing out 500 pounds of gold to every living human being and the financial/political foundations of our civilization would crumble overnight. I am not convinced that would be a bad thing in the long term" -- Michael Rivero
