Water, Planets, and Rational Souls: Science and Faith on Extraterrestrial Life

To the point

Many temperate planets may have liquid water and organic molecules, making life plausible, but Christian theology holds that rational souls are created by God and salvation centers on the Incarnation, with theologians like St. Thomas Aquinas debating what that means for aliens.

Sed Contra: The Science and Theology of Extraterrestrials

Many planets in the Milky Way may host temperate, water-rich worlds with organic chemistry, suggesting habitability but not guaranteeing life; from a Christian perspective rational souls are created by God, making extraterrestrial rational beings possible but not guaranteed, with Catholic scholars divided on how salvation would work and St. Thomas Aquinas even proposing a second Incarnation without negating the first, while the Incarnation remains central to salvation and science and faith together invite reflection on origins, meaning, and humanity's place in a universe potentially teeming with life yet focused on friendship with the Creator.
