Next time that you are away from the towns and cities, wait until it gets dark and then look into the night sky. If you are lucky enough for it not to be raining, you will likely see hundreds of stars in the sky. Each one of these could be a Sun just like our own and each of these Suns could have planets orbiting it. Now times this number a million fold and you can start to fathom the number of stars and planets out there – surely the human race is not a complete fluke and there are aliens out there?
