"Believing that there are little green men who one day will land on earth does not contradict Catholic doctrine, according to the chief of the Vatican's Observatory. Fr. Jose Gabriel Funes told L'Osservatore Romano, the Vatican daily, that such extraterrestrial life "is possible, even if until now, we have no proof." "But certainly in such a big universe this hypothesis cannot be excluded," he told the newspaper."
Belief in space aliens might not contradict Roman Catholic doctrine, but it does contradict the Scriptures. The whole concept of aliens and the resultant alien mania is grounded in an evolutionary worldview. The thought is that since the universe is so vast and so old, there must be alien races out there somewhere. If life sprang from nothing then there must be all kinds of life forms scattered throughout the universe. Without evolution, there can be no aliens.
The concept of space aliens contradicts the Scriptures for a number of reasons. We outlined some of those reasons on the broadcast today.
