We haven't yet found a speck of evidence for biology on another world, so we have no objective way to judge whether life is a onetime fluke or a near-inevitable phenomenon.
Sentiment: NEGATIVE
We know too little about how life began on Earth to lay confident odds. It may have involved a fluke so rare that it happened only once in the entire galaxy. On the other hand, it may have been almost inevitable, given the right environment.
A small, seemingly inconsequential event can determine a life.
Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.
So much of life, it seems to me, is determined by pure randomness.
I think from my experience in war and life and science, it all has made me believe that we have one life on this planet.
Scientists have no agreed theory of the origin of life - plenty of scenarios, conjectures and just-so stories, but nothing with solid experimental support.
I believe life is an intelligent thing: that things aren't random.
So how can we test the idea that the transition from nonlife to life is simple enough to happen repeatedly? The most obvious and straightforward way is to search for a second form of life on Earth. No planet is more Earth-like than Earth itself, so if the path to life is easy, then life should have started up many times over right here.
The origin of life is one of the great outstanding mysteries of science.
Life cannot arise spontaneously but comes only from preexisting life.
