Liam Neeson Quotes

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.

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.

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.

Theoretically, there are planets with an environment that can support life. As yet there is no evidence that there indeed is life on other planets. It's only a matter of time before we get to know.

Where there's water on Earth, you find life as we know it. So if you find water somewhere else, it becomes a remarkable draw to look closer to see if life of any kind is there, even if it's bacterial, which would be extraordinary for the field of biology.

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

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.

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

Up to this day, there has been no proof of the existence of any intelligence other than the human.

Here on Earth, we've found organisms that thrive in environmental conditions we would have once thought uninhabitable. The presence of these extremophiles suggests that life could potentially take hold on worlds other than our own.

Life outside of Earth is probably going to be really hard to find.

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.

I suppose my interest in looking for life elsewhere in the universe really dates back to my teens. What teenager doesn't look up at the sky at night and think am I alone in the universe? Well most people get over it, but I never did and though I made a career more in physics and cosmology than astrobiology I've always had a soft spot for the subject of life because it does seem so mysterious.

The existence of life beyond Earth is an ancient human concern. Over the years, however, attempts to understand humanity's place in the cosmos through science often got hijacked by wishful thinking or fabricated tales.

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

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

I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.

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.

What we expect to find, certainly in our own solar system, are probably simple single or multiple-cell forms of life. To get to intelligent life takes stability of conditions over huge, long periods of time.

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.

The human race may be the only intelligent beings in the galaxy.

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.
