Due to the number of galaxies and the number of stars in each it is highly probable that life exists elsewhere, even if life is so improbable as to occur in 1 x 10^12 solar systems.

One hypothesis states that it is probable given observations, and one hypothesis states that god exists based on nothing more than our current knowledge does not have a natural explanation for a phenomenon. See the difference now?
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
