Yavin: I agree we are most likely alone in the universe. The late Frank Drake and his equation have a lot to answer for along with the sloppy use of countless and infinite. Once they creep into the equation E.T. becomes a certainty, but infinity is a mathematical concept useful in calculus, it doesn't really exist, and even in calculus values only tend to infinity they don't need to get there.
