The only thing that scares me more than space aliens is the idea that there aren't any space aliens. We can't be the best that creation has to offer. I pray we're not all there is. If so, we're in big trouble.

~Ellen DeGeneres

How would it be if we discovered that aliens only stopped by earth to let their kids take a leak?

~Jay Leno

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...

~Neil Armstrong

Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case, the idea is quite staggering.

~Andrew Jackson

Although there may be nothing new under the sun, what is old is new to us and so rich and astonishing that we never tire of it. If we do tire of it, if we lose our curiosity, we have lost something of infinite value, because to a high degree it is curiosity that gives meaning and savour to life.

~Robertson Davies

Although our intellect always longs for clarity and certainty, our nature often finds uncertainty fascinating.

~Karl von Clausewitz

After one look at this planet any visitor from outer space would say "I want to see the manager."

~William S. Burroughs

The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality.

~Edmund Burke

We make our world significant by the courage of our questions and by the depth of our answers.

~Carl Sagan

Personally, I don't think there's intelligent life on other planets. Why should other planets be any different from this one?

~Bob Monkhouse

Interestingly, according to modern astronomers, space is finite. This is a very comforting thought-- particularly for people who can never remember where they have left things.

~Woody Allen

I can assure you that flying saucers, given that they exist, are not constructed by any power on earth.

~President Harry S. Truman, 1950.

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...

~Neil Armstrong

I try to communicate with the life that's out there. I'm serious. It is not that far out. When I'm circling around out there, I try in whatever ways I can to get them to come down here and get me.

~Storey Musgrove

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,"

~Tom Cruise

The nations of the world will have to unite, for the next war will be an interplanetary war. The nations of the earth must someday make a common front against attack by people from other planets.

~General Douglas MacArthur

I am convinced that UFOs exist because I have seen one.

~Jimmy Carter

Given the millions of billions of Earth-like planets, life elsewhere in the Universe without a doubt, does exist. In the vastness of the Universe we are not alone.

~Albert Einstein

Of course it is possible that UFO's really do contain aliens as many people believe, and the Government is hushing it up.

~Stephen Hawking
