Carl Sagan
Extraordinary claims demand extraordinary evidence
Carl Sagan

Carl Sagan

Carl Sagan

Carl Sagan
As the ancient myth makers knew, we are children equally of the earth and the sky.
Carl Sagan
One of the great commandments of science is: 'Mistrust arguments from authority.'
Carl Sagan
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.
Carl Sagan
