just because i think it will happen eventually - there are billions of stars. the cosmos is infinite. when it happens, what would your reaction be? the end of the world? a sign that god wants us to share his word with the newcomers? a sign that the earth and the people on it are not unique, thus affecting our view that man, made in god's image, is special? something else entirely?
i think this is an interesting question so i would appreciate any thoughts.
