Why an Astronaut's Credentials Don't Make a UFO Claim True

By Emma Kim· October 25, 2026

The New York Post reported this week that Charlie Duke, the youngest NASA astronaut to walk on the moon, says UFOs are "demonic" aircraft sent by the devil. Duke flew on Apollo 16. That detail gives the claim a lot of weight in the headline. This article will help you decide how much weight it actually deserves, and gives you a simple test you can reuse the next time a famous name says something startling.

What was reported, and what wasn't

The Post's headline is the main thing we have to go on here: a former NASA moonwalker describes UFOs as demonic and says the devil sent them. That is a statement of religious belief. It is not a report of a measurement, a recording, or an experiment.

That distinction matters. Nothing in the reporting we're drawing on presents new physical evidence, such as radar data, photographs, or a recovered object. What it presents is a person's interpretation of the unexplained, filtered through faith.

Why an astronaut's word carries so much weight

Walking on the moon is among the rarest accomplishments in human history. Astronauts are trained, tested, and trusted with enormous responsibility. So when one speaks, people listen, and that trust feels like it should transfer to everything they say.

Scientists call this the halo effect: we assume someone who is excellent in one area is reliable in others. It's a natural shortcut, and it isn't always wrong. But it is a shortcut.

Expertise is narrower than it looks

Piloting a spacecraft, surviving launch, and conducting lunar fieldwork are real skills. Judging what an unidentified light in the sky is made of, or who sent it, is a different skill. Identifying it takes tools such as sensor data, atmospheric knowledge, and a way to rule out ordinary explanations.

A statement that UFOs are sent by the devil can't be checked with any of those tools. It sits outside what science can test, which is neither an insult to faith nor an endorsement of the claim. It just means the claim belongs in a different category from a finding.

Why people reach for 'demonic' or 'alien' explanations

Humans are pattern-seekers who dislike a blank. When we see something we can't identify, our minds want a story to fill the gap. Which story we pick usually depends on what we already believe.

  • Someone who loves science fiction may see visitors from another world.
  • Someone with a government-secrecy mindset may see a hidden program.
  • Someone with a strong religious framework may see a spiritual force.

The unexplained object is the same in each case. The explanation comes from the person, not the sky. That's a useful thing to notice: a UFO story often tells you more about the storyteller's worldview than about the object.

Why these stories keep going viral

UFOs stay in the public conversation, and claims like this one spread fast for a few reasons. The topic is already familiar, so people engage without needing background. A credible-sounding messenger adds intrigue. And the claim blends two things people love to argue about, science and faith, which guarantees reactions from both sides.

A surprising pairing is also simply shareable: a moonwalker and the devil in one sentence is hard to scroll past.

A quick test for any big claim

Next time a respected figure says something dramatic, ask three questions:

  1. Is this within their field? An astronaut speaking on spaceflight is on firm ground. An astronaut speaking on the supernatural is sharing a personal view.
  2. What's the evidence? Look for something others could examine: data, images, repeatable observations. A belief is not evidence, however sincerely held.
  3. Could it be tested or proven wrong? If no possible observation could contradict the claim, science can't confirm it either.

Applying this test doesn't require doubting anyone's sincerity. Duke's faith may be entirely genuine. The test only separates what a person believes from what has been demonstrated.

What we can say with confidence

UFO, in its literal sense, just means an unidentified flying object: something someone saw and couldn't immediately explain. "Unidentified" is the whole definition. It says nothing about aliens, secret aircraft, or spirits. Those are all guesses that come after the fact.

The most scientifically honest answer to an unexplained sighting is often the least satisfying one: we don't know yet, and we need better data.

The takeaway

Respect the résumé, then check the claim. When a famous expert speaks beyond their specialty, treat it as an opinion worth understanding, and ask what evidence stands behind it before you share it.
