I am very confident that life exists elsewhere in the Universe, this is about the only faith position I hold in life.
I call it a faith position because there is no proof as yet, and may never be, it could well be that we are just too far away for any kind of contact.
But, man moves ever forward, and it will come as no surprise to me if a way is found to establish the existence of life out there.
Certainly there must be many places in the universe, in addition to the ones already confirmed, that are ideal for carbon based life to occur, evolve and flourish.
I sometimes wonder if intelligent life may be found on earth !
