Neil deGrasse Tyson on UFO Files, Trump & Alien Existence (Transcript)

Editor’s Notes: In this thought-provoking episode of Piers Morgan Uncensored, world-renowned astrophysicist Neil deGrasse Tyson explores the mysteries of UFOs, the probability of alien existence, and the implications of upcoming government disclosures. Tyson provides a scientific reality check on what he calls “aliens of our ignorance,” discussing the logistics of government cover-ups and why our smartphone-saturated world still lacks definitive proof of extraterrestrial visitors. The conversation also tackles the future of space exploration through NASA’s Artemis program and the existential threats potentially posed by self-designing AI. It’s an essential guide for anyone looking to separate science fiction from cosmic reality.

TRANSCRIPT:

Are We Being Distracted by UFO Files?

PIERS MORGAN: Well, many cynical people have pointed out that the imminent release of the UFO files is a very convenient distraction for a President who’s fighting many fires with some justification. The same people are concerned that given recent precedent, the UFO files might end up looking something like this.

But all politics aside, the prospect is tantalizing. We could be about to see real evidence of aerial phenomena which even the brightest minds in government have been unable to explain. And it’s not only about flying saucers and little green men. The US Secretary of State Marco Rubio spoke earlier this year about UFOs performing implausible maneuvers above sensitive government sites. We’re talking about rapid acceleration, extreme speeds, trans medium travel. Things which defy the laws of physics as we know them.

All of this conjures excitable talk about both the serious threat to national security and a vast new frontier for science. And it comes at a time when space is firmly back in our hearts and minds. Man and a woman is about to return to the moon. Elon Musk is talking about building AI data centers in space. That’s before he colonizes Mars. Jeff Bezos has a plan to move toxic pollutants into space. And no, it’s nothing to do with Katy Perry.

The question is, are we truly entering a new era of unprecedented discovery and exploration or are we all getting a bit carried away? Well, I can’t think of anyone better to talk to about this, to answer the big questions with some big answers than the astrophysicist and author of the impeccably timed forthcoming book, Take Me to Your Leader, Neil deGrasse Tyson. Neil deGrasse, great to have you back on Uncensored.

NEIL DEGRASSE TYSON: Yeah, Piers, it’s always good to chat with you.

Do Aliens Exist? Separating the Question

PIERS MORGAN: So, look, let’s just cut to the quick. Do aliens exist? Have you ever seen one? Do you think we’re going to be shown evidence of them?

NEIL DEGRASSE TYSON: Well, let’s separate that question into two parts. One of them is, might there be extraterrestrial life elsewhere in the universe? And if you run the numbers, how old is the universe? What are the ingredients of life as we know it? It turns out those ingredients are the most common chemically active ingredients in the universe. And the universe is old. It’s vast. Our galaxy has several hundred billion stars, and there may be as many as a trillion galaxies. And life got underway on Earth almost as quickly as it possibly could have, within about 100 million years. So more than 90% of Earth’s existence, it has had life.

So you just add all that up and you say no one who’s done the math is in denial of there being some kind of alien life somewhere, or perhaps everywhere in the universe. That’s a different question from asking, have intelligent aliens come and visited us here on Earth.

PIERS MORGAN: Right, so what’s the answer? Do you think they have?

Aliens of Our Ignorance: The God of the Gaps Problem

NEIL DEGRASSE TYSON: You got to earn the answer. So it comes down to — let’s back up just a moment. There was a day before we understood much about the physical universe. And it was very easy to ascribe nature and the goings on in nature to gods — God or gods. So a storm would whip up in the ocean, and that was Poseidon wreaking havoc on your town. Maybe somebody did something bad, the lightning bolt would strike. Well, that was Zeus. So things we didn’t understand, the power of a deity was ascribed to it. And philosophers have called that the “God of the gaps.” And it persists even to this day in many people’s thinking. Like if you get ill and you did something wrong, then you have a guilt complex and God is punishing you. It’s “God of the gaps,” because you don’t know why you’re sick or you don’t know how you got sick.

Today, what I find is many people see things they don’t understand. A light in the sky that moves in a way they can’t predict or foresee, and they credit aliens. So for me, crediting things we don’t understand to aliens is the continuation of the “God of the gaps.” But “alien of the gaps” doesn’t have a resonance to it. So in my book, I’ve just introduced a new term: “aliens of our ignorance.” So there’s something you don’t quite understand — aliens. There it is. And it becomes a very convenient way to account for mysteries.

And in science, we love mysteries. We live on the frontier, on the boundary between what is known and unknown in the universe. So if at every time we had an unknown, we said aliens, we wouldn’t have gotten anywhere in our research programs.

Have You Ever Seen Anything Unexplainable?

PIERS MORGAN: Right. So it’s a very, very sophisticated, highly intelligent, incredibly well informed response, actually answering the question. So my more direct question, Neil deGrasse Tyson, is have you seen anything yourself in your entire life where you thought that to me, looks like evidence of extraterrestrial, genuine alien life?

NEIL DEGRASSE TYSON: It’s a great question. And I’ve been looking up to the night sky since I was 9 years old.
