The Vatican's chief astronomer says there is no conflict between believing in God and in the possibility of extraterrestrial brothers" perhaps more evolved than humans. "In my opinion this possibility exists," said the Reverend Jos Gabriel Funes, head of the Vatican Observatory and a scientific adviser to Pope Benedict XVI, referring to life on other planets. "How can we exclude that life has developed elsewhere," he said in an interview with the Vatican newspaper L'Osservatore Romano. The large number of galaxies with their own planets makes this possible, he noted. Asked if he was referring to beings similar to humans or even more evolved than humans, he said: "Certainly, in a universe this big you can't exclude this hypothesis." In the interview headlined, "The extraterrestrial is my brother," he said he saw no conflict between belief in such beings and faith in God. "Just as there is a multiplicity of creatures on earth, there can be other beings, even intelligent, created by God. This is not in contrast with our faith because we can't put limits on God's creative freedom," he said. "Why can't we speak of a 'brother extraterrestrial'? It would still be part of creation." Funes, who runs the observatory that is based south of Rome and in Arizona, held out the possibility that the human race might actually be the "lost sheep" of the universe. There could be other beings "who remained in full friendship with their creator," he said.
