Ann Druyan Quotes

With 'Extinction Machine,' I wanted to start some conversations about whether we're alone in the universe and what that might mean.

I believe that there may be intelligent life on other planets.

How can the human race be, like, the only living form in the universe? There have to be other life forms out there. I believe it.

It's odd that invoking the possibility of alien influences should itself be a sign of madness. I don't see the need for it to explain history on earth, but I can't see any reason why the universe shouldn't be full of life.

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.

We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.

I actually think the chances that we'll find E.T. are pretty good.

It's just too egotistical to think that we are the only lifeform in the universe.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.

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

I think there's all kinds of life out there, including intelligent life, but the reason we haven't found each other is because of vast distances.

I think obviously there is some kind of life form somewhere else. Whether it looks like the creature in 'Alien Autopsy,' I'm not sure.

Human beings have long wondered whether they are alone in the universe.

I don't see why there is no intelligent alien life in the universe.

It's impossible that we're alone in the universe. Every time we think we're more special than others, we're proven wrong.

Is E.T. out there? Well, I work at the SETI Institute. That's almost my name. SETI: Search for Extraterrestrial Intelligence. In other words, I look for aliens, and when I tell people that at a cocktail party, they usually look at me with a mildly incredulous look on their face. I try to keep my own face somewhat dispassionate.

The belief that there are other life forms in the universe is a matter of faith. There is not a single shred of evidence for any other life forms, and in forty years of searching, none has been discovered. There is absolutely no evidentiary reason to maintain this belief.

It doesn't matter how much faith you have or don't have. I just don't buy the idea that we're alone. There's got to be some form of life out there.

I believe in aliens. I think it would be way too selfish of us as mankind to believe we are the only lifeforms in the universe.

Discovering traces of life on Mars would be of tremendous scientific significance: The first time that any signs of extraterrestrial life had ever been detected. Many people would also find it heartening to learn that we're not entirely alone in this vast, cold cosmos.

We're going to understand that there is life on other bodies in the solar system.

I don't think we are the only planet that has life.

People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.
