When you understand the difference between the hypothesis that it is probable that life exists elsewhere(which is based on observation and mathematics), even if the univserse may be too vast for us to directly detect it, and the hypothesis that God created life here on earth(an unfalsifiable claim that is simply an attempt to fill the gaps in knowledge), you will understand the absurdity of your conclusion of what the implication of Dawkins' statement is.
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
