# Avi Loeb comments on alien DNA claims

### Overview  

Astrophysicist **Avi Loeb**, a Harvard professor known for his evidence‑first approach to the search for extraterrestrial life, was interviewed by NewsNation’s **Jesse Webber** on May 22, 2026. The conversation centered on a rapidly spreading claim that a “non‑human or hybrid genetic marker” has been identified in commercial DNA‑testing databases such as Ancestry.com and 23andMe, allegedly pointing to the presence of alien or “Nordic” beings living covertly in the United States. Loeb cautioned that, while the idea is intriguing, it remains **unsubstantiated** and lacks the rigorous peer‑reviewed data required for scientific acceptance.

### The Claim  

The allegation originates from a podcast featuring science‑fiction writer Jason Reza‑Jorjani, who cited former Army sergeant Lyn Buchanan’s purported involvement in a secret CIA remote‑viewing program. According to Buchanan, a CIA analyst named Christopher “Kit” Green believes he can spot extraterrestrial ancestry by looking for an “other” wedge on ethnicity pie charts generated by consumer‑genomics services. Proponents argue that this “other” category could represent a **genetic signature** distinct from any known Earth lineage, suggesting the existence of hidden alien populations.

### Loeb’s Assessment  

When asked whether the story held any scientific merit, Loeb responded:  

> “I don’t think it’s very likely to be a real thing. It’s possible that a CIA analyst or anyone else might be curious, but there is **no scientific basis** to lend credibility to this possibility.”  

He emphasized the biological challenges of interstellar travel, noting that even at light speed a journey would span **tens of thousands of years**, exposing any organism to intense cosmic radiation and low‑gravity environments that would likely degrade DNA. “Humans cannot survive for more than a few years on the surface of the Moon or Mars,” Loeb added, underscoring the improbability of intact alien genomes reaching Earth without extraordinary engineering.

### Scientific Context  

The discussion arrives amid a wave of newly declassified Pentagon UAP (Unidentified Aerial Phenomena) files, which have sparked renewed public interest and calls for systematic study. Loeb, who previously advocated for a **rigorous, data‑driven** investigation of anomalous observations, reiterated that **extraordinary claims require extraordinary evidence**. He urged any researchers pursuing the alleged genetic marker to submit their findings to reputable journals, make raw data publicly available, and allow independent replication. Without such steps, the claim remains speculative and risks conflating **pop‑science** with legitimate astrobiology.

### Looking Ahead  

While the allure of discovering alien DNA in everyday ancestry reports is compelling, the scientific community remains skeptical until reproducible, peer‑reviewed results emerge. Loeb’s interview highlights a broader tension: the desire to explore unconventional possibilities versus the necessity of **methodical validation**. As UAP investigations continue and more data become accessible, experts like Loeb stress that **transparent, interdisciplinary scrutiny**—involving genetics, astrophysics, and planetary protection—will be essential to separate genuine breakthroughs from sensational conjecture. Until such standards are met, the claim of “alien DNA” remains **unverified** and should be treated with caution.
