'Are we alone, I don’t know - the thing is we will probably never know. If we find a civilization that can signal to us, we’ve got to be able to signal to them. If they are a 100 light years away we are talking about a 100 years between every communication, and by then the other one may have died out or they may have not reached the communications technology or we may have blown ourselves up enough to have to start all over again. So we will probably not communicate with anyone out there - not in our lifetime. But there is probably someone. We are so proud that we call them aliens - we may be the aliens. Who knows.'
