We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Stephen HawkingRead
We think that life develops spontaneously on Earth, so it must be possible for life to develop on suitable planets elsewhere in the universe. But we don't know the probability that a planet develops life.
Interpretation
The quote suggests that if life can arise on Earth, it should be possible on other planets, although the likelihood remains unknown.
Stephen Hawking's quote reflects on the natural development of life, implying that our understanding of life's emergence on Earth suggests it could occur in similar conditions on other planets across the universe. However, it also highlights the uncertainty surrounding the probabilities of life existing elsewhere, emphasizing the mystery that still surrounds the origins of life itself.
In practice
This quote could be used in a lecture about astrobiology to illustrate the possibilities of extraterrestrial life.

I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
In my opinion, there is no aspect of reality beyond the reach of the human mind.
That is the essence of science: ask an impertinent question, and you are on the way to a pertinent answer.
We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.
Scientific truth is too beautiful to be sacrificed for the sake of light entertainment or money. Astrology is an aesthetic affront. It cheapens astronomy, like using Beethoven for commercial jingles.
There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.
Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.
If I have put the case of science at all correctly, the reader will have recognised that modern science does much more than demand that it shall be left in undisturbed possession of what the theologian and metaphysician please to term its 'legitimate field'. It claims that the whole range of phenomena, mental as well as physical-the entire universe-is its field. It asserts that the scientific method is the sole gateway to the whole region of knowledge.
