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
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
Carl Sagan
We are star stuff which has taken its destiny into its own hands. The loom of time and space works the most astonishing transformations of matter.
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
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
Who are we, if not measured by our impact on others?
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
We wish to find the truth, no matter where it lies. But to find the truth we need imagination and skepticism both. We will not be afraid to speculate, but we will be careful to distinguish speculation from fact.
Carl Sagan
Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan
If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan (political or religious) who comes rambling along.
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
Looking at fires when high, by the way, especially through one of those prism kaleidoscopes which image their surroundings, is an extraordinarily moving and beautiful experience.
Carl Sagan
If some good evidence for life after death were announced, I'd be eager to examine it but it would have to be real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say, than the comforting fantasy.
Carl Sagan
We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.
Carl Sagan
A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.
Carl Sagan
Man is a transitional animal. He is not the climax of creation
Carl Sagan
Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.
Carl Sagan
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
Carl Sagan
The Bill of Rights decoupled religion from the state, in part because so many religions were steeped in an absolutist frame of mind - each convinced that it alone had a monopoly on the truth and therefore eager for the state to impose this truth on others.
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Carl Sagan
There are lots of ways to communicate what we know, but few ways to communicate what we feel. Music is one way to communicate emotions.
Carl Sagan
