If you set out in a spaceship to find the one planet in the galaxy that has life, the odds against your finding it would be so great that the task would be indistinguishable, in practice, from impossible.
Interpretation
The quote emphasizes the improbability of discovering life in the vast universe.
Richard Dawkins highlights the immense challenges and low probability of finding extraterrestrial life in our galaxy. He suggests that the vastness of space and the rarity of conditions suitable for life make such a quest seem practically impossible, reflecting on the sheer scale and mystery of the universe.
In practice
During a lecture on astrophysics, to illustrate the challenges of extraterrestrial exploration.
No educated person believes the Adam and Eve myth nowadays, but it's surprising how many parents think that it's somehow fun to pass on this falsehood to their children...I would want to argue that the truth of evolution is more interesting and more poetic
If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worst than ignorant, they are the deluded to the point of perversity.
The population of the U.S. is nearly 300 million, including many of the best educated, most talented, most resourceful, humane people on earth. By almost any measure of civilised attainment, from Nobel prize-counts on down, the U.S. leads the world by miles.
When you make machines that are capable of obeying instructions slavishly, and among those instructions are 'duplicate me' instructions, then of course the system is wide open to exploitation by parasites.
Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.
The bitter hatreds that now poison Middle Eastern politics are rooted in the real or perceived wrong of the setting up of a Jewish State in an Islamic region. In view of all that the Jews had been through, it must have seemed a fair and humane solution. Probably deep familiarity with the Old Testament had given the European and American decision-makers some sort of idea that this really was the historic homeland of the Jews.
Even your chin is made up of exploded stars.
No barrier stands between the material world of science and the sensibilities of the hunter and the poet.
I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire.
You see, proteins, as I probably needn't tell you, are immensely complicated groupings of amino acids and certain other specialized compounds, arranged in intricate three-dimensional patterns that are as unstable as sunbeams on a cloudy day. It is this instability that is life, since it is forever changing its position in an effort to maintain its identity--in the manner of a long rod balanced on an acrobat's nose.
Dr. Kertesz mentioned to me a case known to him of a farmer who had developed prosopagnosia and in consequence could no longer distinguish (the faces of) his cows, and of another such patient, an attendant in a Natural History Museum, who mistook his own reflection for the diorama of an ape
Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.
