The Catholic Church has no official teaching on the existence of life beyond the planet Earth. However, many theologians in the Church have speculated on the existence of intelligent life elsewhere in the universe:
Alien Life Out There: Vatican Astronomer’s Take on Extraterrestials
Pope Benedict XVI's Astronomer: The Catholic Church Welcomes Aliens
Catholics are free to speculate away about whether intelligent life exists out there and what it would mean theologically.
