How Would the Discovery of ET Impact Biblical Creation Models?

For the past two millennia, Christian theologians have cited various biblical creation passages to conclude either that ET must exist or that it must not exist. Those favoring an ET interpretation of the Bible cite verses in Job and in Psalm 104 to argue that God enjoys creating life to such a degree that he surely would not stop at creating it on just one planet in the vast universe. Those favoring a no-ET interpretation argue that God is conservative in performing miracles. They cite biblical texts intimating that God limits his miracles to those that are essential for achieving his eternal purposes. Given that God initiated his work of redemption before creating anything (2 Timothy 1:9, Titus 1:2, 1 Peter 1:18-20), they argue that all God’s creation work focuses on bringing an uncountable number of humans into an eternal relationship with him. This redemptive perspective implies that only one planet (physical life site) in the universe is sufficient for God’s purposes to be accomplished.
Today, the book of nature—including recent discoveries in astrophysics, astrobiology, and biochemistry—sheds valuable light on the biblical ET debate. Astrophysical findings indicate that unless the universe is precisely the mass that it is (to within one part in 1060), no life-bearing planet could possibly exist within it. Thus, we see nothing gratuitous or wasteful about the universe’s 2 trillion galaxies.
Astrobiologists, meanwhile, have identified 14 habitability requirements for life. For a planet to house advanced life of any kind, it must reside in a region of space where all 14 of the habitability requirements—or habitable zones—converge. Of the 5,400 planets discovered to date, only 1 resides where even just 3 of the 14 habitable zones overlap, and that is the one we occupy. According to Neil deGrasse Tyson, the more we learn about the universe, the more certain we become that the universe [apart from planet Earth] “is out to kill us.” From the perspective of astrophysics and a biochemistry, ET appears to have no home.
Nevertheless, the discovery of life—the remains of Earth life—on the Moon, Mars, and other solar system bodies is inevitable. Earth’s enormous abundance and diversity of microbes imply that when large meteorites bombard Earth, thousands of tons of Earth rock and soil, including quadrillions of microbes, will be expelled into interplanetary space. Much of this ejected matter, which includes microbial life forms, has been deposited on the Moon, Mars, and other solar system bodies. If we look diligently for these remains, we will find them and, along with it, the answers to some significant biblical questions.
