Ever look up at the sky on a very clear night and wonder what else is going on way out there? Societies of which we will never know about?

There are bazillions of bodies way out there. To think that this little planet earth is the only one that sustains intelligent life is extraordinarily arrogant don'tcha think? What DO YOU THINK or do not worry your pretty little head about it because well it's unknowable so why bother thinking about it?
