Carl Sagan believes the meaning of life is up to us. We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, Carl Sagan believes the meaning of life is up to us. We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, where humanity clings to an obscure clod of rock. The significance of our lives and our fragile realm derives from our wisdom and courage. He further says some 5 billion years from now, after it’s burned to a crisp, or even swallowed by the sun, There will be other worlds and stars and galaxies coming into being and they will know nothing of a place once called EARTH.

The idea of the sense of self-worth comes not from anything we have done, not from anything worthy, but by an accident of birth of humiliation. The meaning of life and purpose of life is on us and we have to define it by staying humble to everyone, making equal rights for everyone, no discrimination, and gender equality.

Carl Sagan pointing the dot in photo capture by Voyager 1 in space from billions of kilometers away – Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor, and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam. Having said that, if we keep meaning of life or a purpose of life small such as to be kind and humble to everyone, helping each other would make a significant difference. Don’t pursue big goals just keep it simple and be conscious of yourself. Carl Sagan meaning of life theory is renowned by many scientist of today’s era.

The meaning of life or a purpose of life is to be conscious and aware at each moment. Carl Sagan quotes are really admirable and keeps you aware in thoughts. Carl Sagan purpose of life is simple and easy to understand for everyone.
