A Quote by Carl Sagan

If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.
Before we go there and set up greenhouses, dance clubs, and falafel stands, let's make sure that, in some subtle form that could be harmed by the human hubbub, life does not already exist there. If not, then by all means build cities, plant forests and fill lakes and streams with trout -- bring life to Mars and Mars to life. We'll then be the Martians we've been dreaming about for all these years.
We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.
We should go to the moon and prepare a base to fire a rocket off to Mars and then go to Mars and colonize Mars. Then when we do that, we will live forever.
I think space exploration is very important. I think there is very intelligent life on Mars. I believe that Martians are spying on us from the bottom of the ocean.
Today we haved touched Mars. There is life on Mars, and it us us-extensions of our eyes in all directions, extensions of our mind, extensions of our heart and soul have touched Mars today. That's the message to look for there: We are on Mars. We are the Martians!
When life partner happens, I hope he is not a youth icon then because I doubt even I would be youthful then. Whether life partner is hot or not, that doesn't matter. He has to be a nice man. He should be funny, responsible, and he should be sweet, and he should love me a lot.
All my life I had lived on the presumption that there was no existence beyond... flesh, the moment of being alive... then nothing. I had searched in superstition... But there was nothing. Then I heard the sound of my own life leaving me. It was so... tender. I regretted that I had paid it no attention. Then I believed in the wisdom of what other men had found before me... I saw that those simple things might be true... I never wanted to believe in them because it was better to fight my own battle. You can believe in something without compromising the burden of your own existence.
I believe that life is valuable, even when it is unwanted, even when it is physically imperfect. I believe our society has a responsibility to defend the vulnerable and the weak. And I believe our nation should set a goal that unborn children should be welcomed in life and protected in law.
First there is a time when we believe everything, then for a little while we believe with discrimination, then we believe nothing whatever, and then we believe everything again - and, moreover, give reasons why we believe.
No one owns anything. Anyone who has lost something they thought was theirs forever finally comes to realize that nothing really belongs to them. And if nothing belongs to me, then there's no point wasting my time looking after things that aren't mine.
It is only when we can believe that we are creating the soul that life has any meaning, but when we can believe it - and I do and always have - then there is nothing we do that is without meaning and nothing that we suffer that does not hold the seed of creation in it.
The mind is everything. If you don’t believe you can do something then you can’t. If you believe that your upbringing was substandard and therefore you have to walk around as a refugee from that crisis situation for the rest of your life, forever bearing the burden of that experience then that will be YOUR life.
I'm sure everybody looked at me cockeyed. But if you don't believe it, then it's not going to happen. If you don't believe it, no one else is going to believe it. But if you believe it and keep saying it, then slowly one person will believe you, then two, then three, then four . . .
Start doing the things you think should be done, and start being what you think society should become. Do you believe in free speech? Then speak freely. Do you love the truth? Then tell it. Do you believe in an open society? Then act in the open. Do you believe in a decent and humane society? Then behave decently and humanely.
The beauty of facing life unprepared is tremendous. Then life has a newness, a youth; then life has a flow and freshness. Then life has so many surprises. And when life has so many surprises, boredom never settles in you.
