Some seem fixated on the idea so NASA funded a group of theologians to try to assess the probable reaction of religious people to extraterrestrial life or intelligent aliens:
One of them, Andrew Davison, has been talking about it of late, not only because of the active pursuit of fossil microbes on Mars but because he is set to publish a book this year, currently titled Astrobiology and Christian Doctrine.
He doesn’t foresee any particular angst among religious believers.
“The headline findings are that adherents of a range of religious traditions report that they can take the idea in their stride,” Davison wrote in “Astrobiology and Christian Doctrine,” a forthcoming book that touches on his time during the program, reported The Times, which obtained portions of the book.
Davison also wrote in the book, which is set to be released in 2022, that the nonreligious community tended to “overestimate the challenges that religious people” might face if evidence of extraterrestrial life were discovered.

That makes sense. The most likely find would be fossil (or even living) microbes somewhere but it’s not clear what they would prove or disprove. Evangelical Christian astronomer Hugh Ross believes, for example, that we will find fossil microbes on Mars but that they probably came from Earth when the planets were less solidly formed and were exchanging materials. It’s not clear that there are any theological implications for that.

Takehome: Theologian and astrobiologist Andrew Davison reports in his forthcoming book that religious acceptance of extraterrestrials is strong and goes back a long way.

Fewer scientists seem to think we can do without any source of intelligence for the creation of the universe. Hence the idea that advanced ET created it.

Avi Loeb writes in Scientific American that when we humans are sufficiently advanced, we will create other universes as well. Avi Loeb’s hypothesis is not logically stranger than the many hypotheses that attempt to account for the Big Bang without underlying information/intelligence.
