Drake Equation - Considerable disagreement on the values of most of these parameters exists. Drake states that given the uncertainties, there are probably between 1000 and 100,000,000 civilizations in the galaxy. {Wikipedia}

Carl Sagan discusses the Drake Equation, which essentially says that there is a very good chance of life on other planets...http://www.youtube.com/watch?v=MlikCebQSlY

Drake's Equation explained by Carl Sagan. The equation estimates that there are "active, communicative extraterrestrial civilizations” in the Milky Way galaxy. Surely, we are not alone.
