Stars out there, give or take a factor of 100. This Kepler project will probably show that most of them have planets. Of course, the speed of light will probably prevent us from bumping into any aliens that may be out there.
If all of recorded history is say 14,000 years, and the universe is 14,000,000,000 years old, then our history is about one one-millionth of the age of the universe. So alien life may have evolved to god-like inteligence, or it may be pond scum, depending on whether they're ahead of or behind us.
It ain't gonna be like Star Trek, where they're neck in neck with us.
