Perhaps we’ve never been visited by aliens because they have looked upon earth and decided there’s no sign of intelligent life.

Neil deGrasse Tyson

I wonder if, in fact, we have been observed by aliens and upon close examination of human conduct and human behavior they have concluded that there is no sign of intelligent life on Earth.

Neil deGrasse Tyson

Intelligent life can't be all that common because it's really rare on Earth and especially since we define ourselves to be intelligent. But in the eyes of an alien coming here who has the technology to make it here, they might observe us and conclude that there's no sign of intelligent life on Earth.

Neil deGrasse Tyson

For all we know, the aliens have already done this and unwittingly concluded that there was no intelligent life on Earth. They would now be looking elsewhere. A more humbling possibility would be if aliens had become aware of the technologically proficient species that now inhabits Earth, yet they had drawn the same conclusion.

Neil deGrasse Tyson

Perhaps I really regard myself as an intelligent man only because throughout my entire life I've never been able to start or finish anything.

Fyodor Dostoevsky

Nobody has ever convinced me that ancient aliens have visited Earth. Not even close.

Dan Brown

Yes, we have been visited and it appears that our visitors are prepared to help us if we allow them. It is a benign contact, however there are those who think that we also have been visited by those who do not wish us well, but I can't speak to that. I just know we have been visited, and I believe that we're being observed, and perhaps we can be helped in a crucial time if we're ready for that.

Edgar Mitchell

Oh, gentlemen, perhaps I really regard myself as an intelligent man only because throughout my entire life I've never been able to start or finish anything. Granted, granted I'm a babbler, a harmless, irksome babbler, as we all are. But what's to be done if the sole and express purpose of every intelligent man is babble--that is, a deliberate pouring from empty into void.

Fyodor Dostoevsky

I'm skeptical of claims that we've been visited by aliens from another planet or other dimension, but I don't rule it out 100 percent. I have an open mind, and I do believe there's other life in the universe.

Leroy Chiao

The CIA agent looked more dead than alive. Alex wondered if he had been hit, but there was no sign of any blood. Perhaps he was in shock.

Anthony Horowitz

I have been privileged to be briefed and to know that we have been visited [by aliens]. I do not have first hand experience in this regard, but I have been on investigating teams and I have been briefed by insiders who do know.

Edgar Mitchell

I always wanted to make aliens that looked like '60s aliens.

Rick Baker

We have never denied that it is possible, indeed probable, that other forms of life, even intelligent life, exist in the universe. But this is different from the belief that we are now being visited by extraterrestrial beings in spacecraft, that they are abducting people, and the there is a vast government cover-up.

Paul Kurtz

The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.

Bill Watterson

I've long been against illegal aliens, partly because they distract us from an even bigger threat: real aliens.

Stephen Colbert

Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified.

Paul Davies
