Astrophysicist Neil deGrasse Tyson argues that the upcoming release of U.S. government files regarding UFOs will likely feel anticlimactic. Despite years of whistleblower testimony before Congress, the public still lacks physical evidence of extraterrestrial life. Tyson suggests that while the documents might offer bureaucratic details, they fail to provide the tangible biological proof necessary to change our understanding of the cosmos.

Pop culture frequently portrays aliens as humanoid, yet Tyson notes that biological diversity on Earth suggests otherwise. Most life forms share no resemblance to humans, making the Hollywood preference for two-eyed, bipedal beings scientifically improbable. He posits that true extraterrestrial life would likely possess no DNA in common with our own, defying the visual tropes found in movies and television.

Humanity's own behavior might dictate how visitors perceive us. Tyson observes that an alien observer might mistake our massive freeway systems for biological structures or mistake celebrities for world leaders. Our history of internal conflict and irrationality suggests that any advanced civilization might find little evidence of true intelligence here. The actual biological reality of an alien remains a mystery.
