Right. Life "here" is unique in that it very well may not exist in a form like our anywhere else but life is certainly not unique. It would be a shame to think that as large as the known universe is that we'd be the only ones to occupy it.Nature happens by chance I think. There are billions of planets out there, orbiting billions of stars. At least one of them is bound to be the right distance for life. If not, then life would, by chance, evolve to survive the environment. If it doesn't survive, it will die and one day a new combination of atoms will bond to make another living thing that can withstand the environment. We just might have been on of the first 'chances' that succeeded.Think about it. Did the 'big bang' created Earth or God created the earth. We are so complex, the distance of earth and the sun has to be exactly perfect. I mean think about it
“The universe is a pretty big place. If it's just us, seems like an awful waste of space.”
-Carl Sagan
Life doesn't have to be carbon based, or made of water, or be bound to the laws which we've discovered, or be limited to the five senses we have. Life is amazingly rezlealant and adaptive and life has had a very very very very long time to come about and perish and restart and foul up and come to be again.
