Would the discovery of extraterrestrial intelligent life have an impact on Catholic theology?

Abstract This study examines the potential impact of the discovery of extraterrestrial intelligent life (ETI) on Catholic theology. The investigation addresses whether the existence of ETIs would challenge core theological principles, particularly the doctrine of Redemption. The study concludes that the discovery of ETIs would not disrupt the foundational tenets of Catholic faith, which is centered on Jesus Christ. The Church has not made any official statements regarding the theological implications of ETIs, reflecting the current speculative nature of their existence. However, the Vatican Observatory is actively involved in research related to potential life-hosting stars, indicating a scientific interest in the topic.
