If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.

More quotes by Carl Sagan
When you realize that no one really knows what they are doing and that everyone is doing the best they can according to their own level of consciousness, life gets a lot easier. Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
Carl Sagan
Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.
Carl Sagan
A googolplex is precisely as far from infinity as is the number 1... no matter what number you have in mind, infinity is larger still.
Carl Sagan
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations.
Carl Sagan
Understanding is a kind of ecstasy
Carl Sagan
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
Carl Sagan
Modern Darwinism makes it abundantly clear that many less ruthless traits, some not always admired by robber barons and Fuhrers - altruism, general intelligence, compassion - may be the key to survival.
Carl Sagan
The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.
Carl Sagan
Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.
Carl Sagan
We live in a society exquisitely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology.
Carl Sagan
There is today-in a time when old beliefs are withering-a kind of philosophical hunger, a need to know who we are and how we got here. It is an on-going search, often unconscious, for a cosmic perspective for humanity
Carl Sagan
The gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.
Carl Sagan
We are a way for the cosmos to know itself.
Carl Sagan
You mustn't think of the Universe as a wilderness. It hasn't been that for billions of years, he said. Think of it more as... ..cultivated.
Carl Sagan
The dumbing down of America is evident in the slow decay of substantive content, a kind of celebration of ignorance.
Carl Sagan
I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign.
Carl Sagan
If we say that God has always been, why not save a step and conclude that the universe has always been?
Carl Sagan
