Quotes & Sayings About Extraterrestrial Life

We inhabit a universe where atoms are made in the centers of stars; where each second a thousand suns are born; where life is sparked by sunlight and lightning in the airs and waters of youthful planets; where the raw material for biological evolution is sometimes made by the explosion of a star halfway across the Milky Way; where a thing as beautiful as a galaxy is formed a hundred billion times - a Cosmos of quasars and quarks, snowflakes and fireflies, where there may be black holes and other universe and extraterrestrial civilizations whose radio messages are at this moment reaching the Earth. How pallid by comparison are the pretensions of superstition and pseudoscience; how important it is for us to pursue and understand science, that characteristically human endeavor. — Carl Sagan

Then she snapped her fingers and we were standing on Europa, discussing the possibility of extraterrestrial life beneath the moon's icy crust. I — Ernest Cline

We feel certain that the extraterrestrial message is a mathematical code of some kind. Probably a number code. Mathematics is the one language we might conceivably have in common with other forms of intelligent life in the universe. As I understand it, there is no reality more independent of our perception and more true to itself than mathematical reality. — Don DeLillo

In order to understand more it is imperative that we improve our knowledge before choosing which side of the fence we feel compelled to belong, — J.P. Robinson

The apparent incompatibility between the abundance of habitable planets in our Galaxy and the lack of extraterrestrial visitors, known as the Fermi paradox, suggest the existence of what Hanson calls a "Great Filter," an evolutionary/technological roadblock somewhere along the developmental path from nonliving matter to space-colonizing life. If we discover independently evolved primitive life in our Solar System, this would suggest that primitive life is not rare, and that the roadblock lies after our current human stage of development-perhaps because assumption 1 is false, or because almost all advanced civilizations self-destruct before they are able to colonize. I'm therefore crossing my fingers that all searches for life on Mars and elsewhere find nothing: this is consistent with the scenario where primitive life is rare but we humans got lucky, so that we have the roadblock behind us and have extraordinary future potential. — Max Tegmark

If you haven't said 'I love you' to someone today, do it. You won't always be happy, but you should try to be. Don't be too afraid of germs. Those people have no fun. Remember to look around sometimes. You might see something you haven't seen before or at the very least avoid being hit by a flying object. Speaking of flying objects, don't spend your life looking for extraterrestrial life, unless you work for NASA. Remember that you always have to cooperate with someone. Life is an endless negotiation. Play fair. Stay out of jail. Don't live in the past. Eat breakfast. It really is the most important meal of the day. Try to make new friends, even when you think you're too old to do that ... And finally, remember this 'Yes' is always a better work than 'no'. Unless, of course, someone has just asked you to commit a felony. — Lisa Lutz

I don't believe in a conspiracy to hide the existence of extraterrestrial life. — David Duchovny

Ann Druyan suggests an experiment: Look back again at the pale blue dot of the preceding chapter. Take a good long look at it. Stare at the dot for any length of time and then try to convince yourself that God created the whole Universe for one of the 10 million or so species of life that inhabit that speck of dust. Now take it a step further: Imagine that everything was made just for a single shade of that species, or gender, or ethnic or religious subdivision. If this doesn't strike you as unlikely, pick another dot. Imagine it to be inhabited by a different form of intelligent life. They, too, cherish the notion of a God who has created everything for their benefit. How seriously do you take their claim? — Carl Sagan

I'm frequently asked, "Do you believe there's extraterrestrial intelligence?" I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren't extraterrestrial intelligence, but of course there is as yet no compelling evidence for it.
Often, I'm asked next, "What do you really think?"
I say, "I just told you what I really think."
"Yes, but what's your gut feeling?"
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it's okay to reserve judgment until the evidence is in. — Carl Sagan

In very different ways, the possibility that the universe is teeming with life, and the opposite possibility that we are totally alone, are equally exciting. Either way, the urge to know more about the universe seems to me irresistible, and I cannot imagine that anybody of truly poetic sensibility could disagree. — Richard Dawkins

When I was a child and told my mother I didn't felt this was my planet, she thought I was schizophrenic or autistic. When later I finished a college degree and started working in different countries, she called me monster and started threatening me. Nearly 40 years later, when I was making a living from the books I wrote based on what I know, and making 6 times more money than she ever will, she apologized. I'm just not sure why or what she was apologizing for. I had already forgiven her ignorance when realizing nobody would ever believe the truth but myself. I had to go the whole way alone. Nobody was going to come with me on this very long, painful and challenging journey that humans call life but for me was much more than that, it was my mission, of changing their whole future far beyond the time when I'm gone. She was never my mother but merely the human body that gave me birth. In that sense, I am a monster, because I had no love. I had to find that too, on my own. — Robin Sacredfire

The term "exobiology," sometimes interchanged with astrobiology, is actually much more specific - it covers the search for life beyond Earth and the effects of extraterrestrial environments on living things. Today, it is considered a subdiscipline within astrobiology. — Cris Putnam

In our time the search for extraterrestrial life will eventually change our laws, our religions, our philosophies, our arts, our recreations, as well as our sciences. Space, the mirror, waits for life to come look for itself there. — Ray Bradbury

It is one thing to speak of embracing the new, the fresh, the strange. It is another to feel that one is an insect, crawling across a page of the Encyclopedia Britannica, knowing only that something vast is passing by beneath, all without your sensing more than a yawning vacancy. — Gregory Benford

The biggest breakthrough in the next 50 years will be the discovery of extraterrestrial life. We have been searching for it for 50 years and found nothing. That proves life is rarer than we hoped, but does not prove that the universe is lifeless. We are only now developing the tools to make our searches efficient and far-reaching, as optical and radio detection and data processing move forward. — Freeman Dyson

Tom's theory of why human beings had yet to receive any message from extraterrestrial intelligences was that all civilizations, without exception, blew themselves up almost as soon as they were able to get a message out, never lasting more than a few decades in a galaxy whose age was billions; blinking in and out of existence so fast that, even if the galaxy abounded with earthlike planets, the chances of one civilization sticking around to get a message from another were vanishingly low, because it was too damned easy to split the atom. — Jonathan Franzen

Well, what the fuck would an extraterrestrial life form want to come here for? — Matt Haig

You have to think if we've been visited by extraterrestrial life, it was like a zookeeper walking into the chimp enclosure: He looks around, takes some pictures, then leaves without interacting significantly with the environment. Meanwhile the chimps have no idea what the fuck just happened. — J. Richard Singleton

It is striking that the observational search for extraterrestrial life began in the same generation as the invention of the telescope, and with the greatest theoretician of the age. — Carl Sagan

We are so used to the notion of our own inevitability as life's dominant species that it is hard to grasp that we are here only because of timely extraterrestrial bangs and other random flukes. The one thing we have in common with all other living things is that for nearly four billions years our ancestors have managed to slip through a series of closing doors every time we needed them to. — Bill Bryson

A time will come when men will stretch out their eyes. They should see planets like our Earth. — Christopher Wren

Extraterrestrial intelligence could have sent DNA-seed packets out through space to plant life on hospitable planets such as earth. — Timothy Leary

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. — Nick Bostrom

The fancy that extraterrestrial life is by definition of a higher order than our own is one that soothes all children, and many writers. — Joan Didion

It's only fashion that has said the pendulum has swung from extreme skepticism about extraterrestrial life to extreme credulity. The truth is somewhere in between. — Paul Davies

[O]ver the years I travelled to another universe. However alert we are, however much we think we know what will happen, antiquity remains an unknown, unanticipated galaxy. It is alien, and old people are a separate form of life. They have green skin, with two heads that sprout antennae. They can be pleasant, they can be annoying
in the supermarket, these old ladies won't get out of my way
but most important they are permanently other. When we turn eighty, we understand that we are extraterrestrial. If we forget for a moment that we are old, we are reminded when we try to stand up, or when we encounter someone young, who appears to observe green skin, extra heads, and protuberances. — Donald Hall

Discussing the possibilities of extraterrestrial life: I would love it even if they were short, sullen, grumpy and sexually obsessed. But there just isn't any good evidence. — Carl Sagan

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. — Ann Druyan

The Federal government does not have any information about extraterrestrial life to conceal, and there are no secret projects for me to investigate. — Orrin Hatch

This afforded an opportunity for a close encounter with Earth as it might appear to an alien spacecraft, and Carl Sagan proposed using this as a "control experiment for the search for extraterrestrial life by modern interplanetary spacecraft." The instruments detected the spectral signature of the chlorophyll from green plants, and signs of an obviously life-altered atmosphere. As Sagan and colleagues wrote in their paper "A search for life on Earth from the Galileo spacecraft" published in Nature, they found evidence of abundant gaseous oxygen, a widely distributed surface pigment with a sharp absorption edge in the red part of the visible spectrum, and atmospheric methane — David Grinspoon

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 modern belief that highly advanced civilizations from other planets are visiting the Earth via spacecraft is a ruse. If real, they are beings created apart from the procreative processes established for life on Earth (Gen. 1). And since they are not direct creations of God Himself, their origins must be sought from other sources. — Jeffrey W. Mardis

I'm pretty sure I locked that door," Daemon growled.
Luc set the box of doughnuts down, and I eyed them like they held the answer to life. "And I'm pretty sure I let myself in. Hey, Katy!"
I jumped at my name. "Hey, Luc.."
"Look at what I got." He dug into his bag and pulled out an extraterrestrial highway shirt. "We can be soul twins now. — Jennifer L. Armentrout

In the Year 2000 the discovery of extraterrestrial life will create a revolution in science, art, and pornography. — Conan O'Brien

Once He created the Big Bang ... He could have envisioned it going in billions of directions as it evolved, including billions of life-forms and billions of kinds of intelligent beings. As a theologian, I would say that the proposed search for extraterrestrial intelligence (SETI) is also a search of knowing and understanding God through his works - especially those works that most reflect Him. Finding others than ourselves would mean knowing Him better. — Theodore Hesburgh

The evidence that at least one extraterrestrial civilization has visited Earth is extensive both in scope and detail. In its totality it comprises a body of evidence which at the very least supports the general assessment that extraterrestrial life has been detected, and that a vigorous program of research and serious diplomatic initiatives is warranted. — Steven M. Greer

This moment of lucidity does not last long. But it serves as the punishment for your sins, a Promethean entrails-pecking moment, crouching half-horse half-man, with the knowledge that you cannot appreciate the destination without knowing the starting point; you cannot revel in the simplicity unless you remember the alternatives.
And that's not the worst of your revelation. You realize that the next time you return here, with your thick horse brain, you won't have the capacity to ask to become a human again. You won't understand what a human is. Your choice to slide down the intelligence ladder is irreversible. And just before you lose your final human faculties, you painfully ponder what magnificent extraterrestrial creature, enthralled with the idea of finding a simpler life, chose in the last round to become a human. — David Eagleman

It amazes me how people can close their minds off to the size of the Universe. With billions of stars, millions of galaxies, and possibly a googol of planets, how can it be that human beings are the only thinking animal in creation? — Coriander Woodruff

Most visions of extraterrestrial life are actually steeped in human hubris. The fictional extraterrestrials of 'Star Trek' or a hundred other space operas are less alien than many of my neighbors. And funny, the ones running the place are mostly WASPish men. — Nathan Myhrvold

For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas. — George Smoot
