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.

More quotes by Carl Sagan
Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
We are made of starstuff.
Carl Sagan
Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.
Carl Sagan
Those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.
Carl Sagan
A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
Carl Sagan
A millennium before Europeans were willing to divest themselves of the Biblical idea that the world was a few thousand years old, the Mayans were thinking of millions and the Hindus billions.
Carl Sagan
We are prodding, challenging, seeking contradictions or small, persistent residual errors, proposing alternative explanations, encouraging heresy. We give our highest rewards to those who convincingly disprove established beliefs.
Carl Sagan
If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.
Carl Sagan
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
As the ancient myth makers knew, we are children equally of the earth and the sky.
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
Somewhere, something incredible is waiting to be known.
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.
Carl Sagan
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Carl Sagan
Science is an attempt, largely successful, to understand the world, to get a grip on things, to get hold of ourselves, to steer a safe course. Microbiology and meteorology now explain what only a few centuries ago was considered sufficient cause to burn women to death.
Carl Sagan
The notion that science and spirituality are somehow mutually exclusive does a disservice to both.
Carl Sagan
It does no harm to the romance of the sunset to know a little bit about it.
Carl Sagan
First rule in government spending: why build one when you can have two at twice the price?
Carl Sagan
