Eugene Cernan Quotes

It is probable that extraterrestrial life existed somewhere in the universe.... I am not sufficiently conceited to think that my sun is the only one with a family of planets. I, for one, am not so immensely impressed by the success we are making of our civilization here that I am prepared to think we are the only spot in this immense universe which contains living, thinking creatures, or that we are the highest type of mental and physical development which has ever appeared in the vast compass of space and time.

Perhaps, as some wit remarked, the best proof that there is Intelligent Life in Outer Space is the fact it hasn't come here. Well, it can't hide forever - one day we will overhear it.

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

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.

It's not going to be just humans colonizing space, it's going to be life moving out from the Earth, moving it into its kingdom. And the kingdom of life, of course, is going to be the universe.

I believe there's other forms of intelligence in the universe. I've seen and heard some pretty convincing UFO stuff. Besides, if we're the most intelligent things in the universe... well, that's just depressing.

We have no proof, But if we extrapolate, based on the best information we have available to us, we have to come to the conclusion that ... other life probably exists out there and perhaps in many places.

The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.

It's time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

This planet seems to be in such sorry shape. And I can't ever think about the rest of the universe without coming back home and thinking what the implications for life here would be if we were to really have some definitive proof of extraterrestrial life.

Life exists throughout the cosmos and is a consequence of matter in the universe.

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.

One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.

The universe is large and old, and the ingredients for life as we know it are everywhere, so there's no reason to think that Earth would be unique in that regard. Whether of not the life became intelligent is a different question, and we'll see if we find that.

If we do discover more than one type of life on Earth, we can be fairly certain that the universe is teeming with it, for it would be inconceivable that life started twice here but never on all the other earth-like 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.

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

I think that it would be unwise of us not to believe that there is life outside of us, intelligent life. And so I do believe in aliens.

As a science fiction writer, it's hard to think of a more stirring theme than the origin and ultimate destiny of life in the universe.

It's presumptuous for us to think we are the only beings in the cosmos.

I don't want to believe that we're the only beings out there, because to me, that's even scarier than there being other life forms. I think I always like the idea of there being something a little bit crazier than us out there.

Astrobiology is the science of life in the universe. It's an attempt to scientifically deal with the question of whether or not we're alone in the universe, looking at the past of life, the present of life, and the future of life. It's an interdisciplinary study incorporating astronomy, biology, and the Earth sciences.

There's planets, life in the universe. You don't talk about that in high school - or maybe I skipped class that day.

I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.
