Is there intelligent life out there? I don't know. To believe either way surely requires a leap of faith. And I'm particularly good at sitting on the fence, so that's where I'll stay.
But it's fun to talk about these things. I sometimes like to think that life is not restricted to the definition of earth-bound scientists. That perhaps it could exist in other forms, in other types of energies. Maybe there's life in neutrinos? Passing through all different kinds of matter, like some kind of 'force'... ooooh! Or maybe quasars are the egg sacks for ancient alien races?
