" "He argued that we are so helpless at birth that, if the first human infants had been put into the world on their own, they would immediately have died. From this Anaximander concluded that human beings arose from other animals with more self-reliant newborns: He proposed the spontaneous origin of life in mud, the first animals being fish covered with spines. Some descendants of these fishes eventually abandoned the water and moved to dry land, where they evolved into other animals by the transmutation of one form into another.

About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan
I've been searching, Eleanor. After all these years, believe me, I know the truth when I see it. Any faith that admires truth, that strives to know God, must be brave enough to accomodate the universe. I mean the real universe. All those light-years. All those worlds. I thing of the scope of your universe, the opportunities it affords the Creator, and it takes my breath away. It's much better than bottling Him up in one small world. I never liked the idea of Earth as God's green footstool. It was too reassuring, like a children's story... like a tranquilizer. But your universe has room enough, and time enough, for the kind of God I believe in.

The Cosmos extends, for all practical purposes, forever. After a brief and sedentary hiatus we are resuming our ancient nomadic way of life. Our remote descendants, safely arrayed on many worlds though through the Solar System and beyond, will be unified by their common heritage, by their regard for their home planet, and by knowledge that, whatever other life may be, the only humans in all the Universe come from Earth.
