" "600 million years ago, the monopolizing grip of the algae was broken and an enormous proliferation of new lifeforms emerged, an event called the Cambrian explosion. Life had arisen almost immediately after the origin of the Earth, which suggests that life may be an inevitable chemical process on an Earth-like planet.

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
She began to understand why lovers talk baby talk to one another. There was no other socially acceptable circumstance in which the children inside her were permitted to come out. If the one-year-old, the five-year- old, the twelve-year-old, and the twenty-year-old all find compatible personalities in the beloved, there is a real chance to keep all of these sub-personas happy. Love ends their long loneliness. Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.
Cosmos is for many that first encounter with the universe that you thought was foreclosed to you because you couldn’t do the math, or you live in a place where there are no scientists to invite you in. Carl wanted everyone to come on this voyage; to experience the power of the scientific perspective and the wonders it reveals. His secret was to recapture the person he was before he understood the concept and then retrace his own thought steps toward comprehension. It worked. He inspired legions to study, teach, and do science.
