Using the "Drake equation" there are 1.8 trillion planets that support life, 180 billion of those have advanced life (plants and animals) 1.8 billion of those have intelligent life, 180 million of those have intelligent life as advanced as us, and 1.8 million of those have intelligent life that is more advanced then us. This of course is calculating the entire universe.
Absolutely!!! We are only one galaxy in the universe... There are places so far away that you nor I could live long enough to travel there. I would be shocked to find there is NOT life other than on Earth.
