When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules.

More quotes by Carl Sagan
I think if we ever reach the point where we think we thoroughly understand who we are and where we came from, we will have failed.
Carl Sagan
Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years it still takes my breath away.
Carl Sagan
We are made of starstuff.
Carl Sagan
Who are we, if not measured by our impact on others? That’s who we are! We’re not who we say we are, we’re not who we want to be - we are the sum of the influence and impact that we have, in our lives, on others.
Carl Sagan
Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.
Carl Sagan
If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.
Carl Sagan
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan
Religions are often state-protected nurseries of pseudoscience, although there's no reason why religions have to play that role. In a way, it's an artefact from times long gone.
Carl Sagan
The method of science, as stodgy and grumpy as it may seem, is far more important than the findings of science.
Carl Sagan
There is in this Universe much of what seems to be design.
Carl Sagan
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
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.
Carl Sagan
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
Carl Sagan
Somewhere, something incredible is waiting to be known.
Carl Sagan
And you are made of a hundred trillion cells. We are, each of us, a multitude.
Carl Sagan
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
If you want to make a [rhubarb] pie from scratch, first you have to create the universe.
Carl Sagan
For all I know we may be visited by a different extraterrestrial civilization every second Tuesday, but there's no support for this appealing idea. The extraordinary claims are not supported by extraordinary evidence.
Carl Sagan
