He is an alien,
people don't talk to each other on the bus in case they are talking to a ******* nut case.
I won't give you away your secret is safe!
Like someone once said...
We are either completely alone in the universe, or we are not. Both scenarios are equally frightening.
But maybe others are watching the Aliens and they did not tell You?
They are among us. Living, not paying any taxes, just waiting to pounce!
I think that it's highly unlikely that we are completely alone in the universe. Because the chances have to be pretty high that there's at least one planet with some sort of hospitable life on it. If you imagine how many planets there are in our solar system, and then how many in the entire universe, there's got to be a pretty good chance of at least one planet with an atmosphere and living conditions that are ripe for life.
Or reptilian... quite popular race on the tube...
I oftren think that we've already been contacted by aliens. I mean it's a large universe out there. there has to be other aliens looking and searching for life as well as we are.
