Life in our universe

Recent estimates have put the number of galaxies in our known universe to be in the area of 100 billion. When you look at our own Milky Way galaxy, our sun is only one of 200 billion other stars within the galaxy (http://hypertextbook.com/facts/1999/TopazMurray.shtml). This being said, it is obvious that the universe is ungodly huge. How can anyone logically believe that there is no other life in our universe? How many other little rocks floating around one of trillions of stars in our universe have been lucky just like our planet to be able to foster life? People who preach intelligent design say that the liklihood of our existence on this planet is rediculously low, and that alone gives evidence for some sort of higher power. However when one considers the scope of the universe, how can anyone say that we are the only planet that is sustaining life? I just find it hard to believe that we should single our planet out from the trillions of others in our universe. Anyone agree or disagree?
