Paul Davies Quotes

The Eerie Silence: are we alone in the universe?

That is a big question we all have: are we alone in the universe? And exoplanets confirm the suspicion that planets are not rare.

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

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.

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.

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.

I think there must be some other life forms, even if they're microscopic.

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

The discovery of any kind of life [in Space] at all would be a tremendous watershed moment in biology, as well as all of science.

As the romance of manned space exploration has waned, the drive today is to find our living, thinking counterparts in the universe. For all the excitement, however, the search betrays a profound melancholy - a lonely species in a merciless universe anxiously awaits an answering voice amid utter silence.

If we're looking for intelligence in the universe I think everybody assumes that this has to start with life and so the question is: "How likely is it that there will be life elsewhere in the universe?"

Yes, of course. Are you really so arrogant as to believe we are alone in this universe? Millions of stars, and we're supposed to be the only living creatures? No, there are many things out there, we just don't know.

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

It might be arrogant to think that we're the only living creations in all of the solar systems that there are. Space is so vast.

I've always been fascinated by physics and cosmology. It gets more and more scary the older you get.

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.

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

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.

I think the mystery of what's out there in the universe is just very compelling.

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.

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.

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

Are we alone? Many, many people on planet Earth want to know. We are on the cusp of being able to answer that question... because of the investments we're making in space technology.

The building blocks of life are readily available throughout the universe.

I believe we are the only sentient beings in the universe, and I believe that 500 years from now, we will still be the only sentient beings around.
