I disagree. Writers such as Chesterton,Lewis, Wright, etc have found, the existence of Extraterrestrials would not damage Catholicism (or any Earth religion for that matter). Instead, it might actually inspire and reinvigorate them as both an opportunity to bring their words to a new civilization, and as proof of divine handiwork in creating similar life..
There is also the possibility that these alien beings are religious themselves, leading to a greater diversity of faith.
