The linked article discusses the possibility of life being found on some rocky planet. The conversation is meaningless as far as I am concerned for several reasons. 1) It was no surprise that rocky planets are out there 2) Even if there wasn't rocky planets out there gas planets would be capable of having its own form of truly alien life 3) there are no religious qualms with life on other planets.
In the ancient Christian past, great minds like Saint Augustine of Hippo stated there could be no land outside of the European/Asian/African core. His geographical theology was shattered by the discovery of the new world. If there could be another hemisphere outside of the Jewish/Christian reach, why not whole worlds?
