Overview
Astrophysicist Avi Loeb is examining whether public narratives about unidentified aerial phenomena (UAP) can develop and spread in ways that resemble religious myths. In a post published October 30, 2026, Loeb presents the comparison as a question about how people form beliefs—not as evidence that UAP reports are religious in origin or that any particular sighting has been explained.
The central distinction in Loeb’s discussion is between belief based primarily on conviction and knowledge tested against evidence. “A system of statements based on conviction rather than evidence is closer to religion than it is to science,” he writes, while acknowledging that many scientists are also religious and understand the difference between religious belief and scientific knowledge.
Evidence, Conjecture and Belief
Loeb argues that science differs from politics and religion through its willingness to allow empirical evidence to settle disputes. Human beings routinely construct stories to explain incomplete information, he notes, and scientific research itself includes conjectures and unproven theories. The difference, in his view, is that scientific hypotheses remain provisional and must ultimately be tested through observations or experiments.
He uses the history of quantum mechanics to illustrate the process. Although quantum entanglement once appeared deeply counterintuitive, experiments by Alain Aspect, John F. Clauser and Anton Zeilinger helped establish the phenomenon; the three scientists received the 2022 Nobel Prize in Physics for their work. Loeb contrasts that evidence-based progression with unresolved questions such as how to reconcile quantum mechanics and gravity. The lack of experimental support for theories involving extra dimensions or supersymmetry, he says, does not make those theories religious myths because researchers recognize that evidence is still required.
The UAP Storytelling Question
Applied to UAP, the argument raises a question about what happens when compelling accounts circulate in an environment where decisive data is limited, inaccessible or of poor quality. Witness testimony, videos and official statements may prompt legitimate investigation, but they do not automatically establish the cause, origin or nature of an observation.
Loeb suggests that uncertainty can create space for narratives to acquire authority through repetition, confidence and social reinforcement. In politics and religion, he writes, conviction can attract attention and approval on social media. Scientific inquiry, by contrast, cannot determine physical reality through confidence alone, regardless of how sophisticated the theorist or technology may be. The quality of the underlying data remains decisive.
Human Perception and Incomplete Information
The post also connects scientific reasoning to ordinary perception. Human biological sensors collect information about the world, but those signals are often incomplete. Loeb offers the example of a cat that appears to walk toward a building and later emerges on the other side. An observer may reasonably infer that it was the same cat throughout, even though the building temporarily blocked the view. Other explanations—including the possibility of multiple identical cats—are imaginable, but observation is needed to distinguish among them.
That example reflects a broader issue in UAP investigations: an unexplained observation is not necessarily evidence for the most dramatic explanation. Loeb’s essay therefore functions less as a report of new UAP findings than as a methodological reflection on how unexplained events become stories. Its comparison with religious myth is presented for consideration, with the underlying message that durable conclusions about UAP require transparent, high-quality measurements and tests that could potentially disprove competing explanations.
