Religions for many is what psychologist would call an "anchoring heuristic." What that means is that it is the anchor for their world view. A starting point or filter to understand most everything else. In the past "why does it rain?" "why do people get sick?" "why do people speak different languages?" "why are their earthquakes?" all had their answer with God, The Bible, or whatever version of holy scripture or belief one had been raised with or adopted. Now it's widely understood why it rains, what causes most illnesses, and how language has evolved through our sciences, such that we can predict rain, heal many diseases, and see the evolution of languages across time, as well as understand why some places have more earthquakes because of plate tectonics, which was ridiculed when first presented as a theory.
UFOs are the one of the biggest of mysteries that we don't understand well: and one that, like disease and earthquakes is scary at times. Just like people looked to the bible as clear evidence of disease and earthquakes being God's judgement with The Plagues of Egypt in Exodus, David's Census and the Plague in 2 Samuel 24, Miriam's Leprosy in Numbers 12 and Uzziah's in 2 Chronicles 26 and understood Earthquakes in Isaiah 29 and Ezekiel 38 as signs of God, some people will be tempted to look at NHI (non-human intelligence) and try to fit it into a biblical/religious narrative.
However, what we've found is that just like with the things already mentioned science has done a far superior job understanding the material world despite often intense religious pushback and cognitive dissonance. Galileo was sentence to house arrest until he died for supporting what Copernicus figured out with observation and math that the Sun, not the earth, was the center of the solar system (though at the time they thought it was the universe). It says in the bible in Ecclesiastes 1:5: "The sun rises and the sun sets, and hurries back to where it rises." And in Psalm 93 93:1: "The world is firmly established; it cannot be moved." Passages like these made it very clear to many that it was heretical and against the divine word of God that the earth could was not the center of all creation and moving around the sun. Another examples is the age of the earth with famously James Ussher trying to calculate the age of the world through biblical genealogies and came with the the earth being created in 4004 BC. now we know we radioactive dating that it's closer to 4.54 billion years old. There are others, but the last one I will mention is the creation of species. Genesis describes species being created according to their "kinds." Because of this most people, particularly religious people, didn't believe the ideas first put forward by Darwin that species evolve. However, evidence has been built up over time to show the links between species that even the Catholic Church and many others accept evolution, and we routinely go to hospitals for treatments, and everyone believes the sun is the center of the solar system which is not even the center of the Milky Way, which is 1 of billions of galaxies.
Gallileo was sentenced to house arrest for saying the sun was at the center of the universe. Imagine the trouble he would have been in if he explained this picture at the time.
Smallpox, Polio, Measles, Tetanus, Rabies, and others are all curable or preventable with moden science. Vaccines aren't always perfect, but compared to you or your child getting Polio or getting Rabies (which is otherwise 100% fatal), I'll take them.
When it comes to UFOs I think we are seeing a slow acceptance by some that there indeed may be other intelligence life in the universe. The Catholic Church as been open to the possibility of alien life (see below), and many other religions have either long-believed or have started to accept the possibility.
Science May Do Better, But it Doesn't a Free Pass Either
Like is says above science doesn't get a pass either. While Science has cured diseases, launed satellites, built airplanes, harness electricity and built the internet. Scientist have sometimes gotten so confident that they KNOW what reality is that they too have been unyielding to better data and have persecuted people for thinking things that have ultimately proven to be right. In the 1840s is was discovered by Ignaz Semmelweis that doctors washing their hands before delivering babies caused fewer deaths. Doctors pushed back and his ideas were ridiculed. I already mentioned plate tectonics before and how the idea was considered absurd by the geologists at the time, as well as scientist saying meteorites couldn't exist because "there are no rocks in space." The idea that bacteria caused ulcers caused Barry Marshall to be ridiculed, until he drank a culture of bacteria and developed gastritis. The idea of a static universe was the accepted norm, even by Einstein until observations showed it was expanding with later Einstein calling his "greatest blunder." Prions showed that not all disease needed DNA or RNA challenging a fundamental idea in biology. and thousands of sailors could have been saved from scurvy had the navies of the world more quickly accepted the theory, There are other examples, some I mentioned already, like germ-theory replacing Miasma, the idea of the 4 elements (earth, water, fire, and air), the concept of Ether, the rejection of now accepted neuroplasticity and adult neurogenesis, and there will be more to come.
The Challenge NHI, Disclosure, and/or Open Contact Will Bring
One of the biggest challenges will be what will the NHI tell us about the world that many still use scripture or science (that NHI will instantly update perhaps) to understand. For example If NHI made contact with people in the 1600s and told us that microorganisms caused most sickness it would be shocking, and many people might be in disbelief claiming that it's clear that disease is from God, the devil, sin, bad air, etc... What if aliens told us in 1300 AD that Humans were cousins to apes and we share 96% of our DNA with them ? Or told us in 1400 that stars are just other suns and we orbit ours just like there are other planets orbiting their suns? All of these revelations would have been such ontological shock and so distressing you might get a surge in end-time and death cults (which have happened with almost all of the big moments in history), demonic theories, or even a rejection of all science. What will we get told? We can only take guess and many have... That we are seeded here, that our model of physics is wrong in fundamental ways, that consciousness is not something unique to humans or even generated by your brain (it just receives/'filters it), that the afterlife exists but is not even close to what many people thought? That there are other "dimensions?" Who knows. But we need to realize that our understanding of reality, whether through religion, or science has often been wrong throughout history no matter how confident we've been, and surely must also then be somewaht today, even if we're further along. More, that beliefs and practices have changed in both religion and science. Close to 100% of Christians don't use the bible to justify slavery anymore (despite Ephesians 6:5, 1 Timothy 6:1-2, etc.). And despite past interpretations of scripture, Protestants now regularly ordain women (despite 1 Timothy 2:1-12, 1 Corinthians 14: 34-35, etc.). Divorce is much more accepted (despite Jesus himself in Mark 10: 11-12, and 1 Corinthians 7: 10-11, etc.). Further, many churches used scripture to teach alcohol was sinful and no longer do so (despite Proverbs 20:1, Romans 14:21, etc.), and now except for the Amish and few other groups, many more women now feel it's acceptable to get dressed up, even for church (despite 1 Timothy 2:9–10 , 1 Peter 3:3–4 , etc.). And those are just some of the more recent 20th century examples. Science has many examples of belief changing based up better equipment, new discoveries, and more. The paragraph above this one mentions a few of these. It's the distressing shock that some people think will happen to the world view of too many people that's sometimes cited as a reason for the decades long cover-up. I hope we can be better than that.
Here's a response I typed to a YouTube user directing me to a video about demons and aliens and how some must be demons:
Quantum physics contradicted classical physics so much that even great scientist at the time couldn't believe time dilation, superposition, and gravity and space-time being intertwined, etc... Now, it's just standard physics. My point is that a pastor who believes in demons are going to see demons in craft he can't explain, when really the answer is he just can't explain it. Scripture was used to explain how the earth is at the center of the universe Psalm 93 93:1: "The world is firmly established; it cannot be moved." and now we know that's not true. It was used to describe the age the the earth, and how languages differed and more. All things science later figured out. My point it that scripture is a poor guide to use to understand how things that we see and touch work. It's o.k. simply to not know and have humility and that goes for scientists too by the way. But I would bet science will find the answer before religion, just like science built the internet I am now typing across as well as the Mars lander, antibiotics, GPS, etc...Religion hasn't built much. But it does give us hope, solace, community, and other very important things. (typos taken out for my webpage)
