How Did Life Arise on Earth?
But despite knowing approximately when life first appeared on Earth, scientists are still far from answering how it appeared.
"The solution of a mystery of this magnitude is totally unpredictable," said Freeman Dyson, a professor emeritus of physics at Princeton University in New Jersey. "It might happen next week or it might take a thousand years."

Scientists do not have concrete evidence to support their work but the findings are significant in understanding the possible origin of life on Earth. If the theory is proven, it can be one of the biggest achievements in the scientific field.

The Secret of how life on Earth Began
How did life begin? There can hardly be a bigger question. For much of human history, almost everyone believed some version of "the gods did it". Any other explanation was inconceivable.
That is no longer true. Over the last century, a few scientists have tried to figure out how the first life might have sprung up. They have even tried to recreate this Genesis moment in their labs: to create brand-new life from scratch.
So far nobody has managed it,

The mystery behind the origin of life
"Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled." — Paul Davies (The Fifth Miracle)

It’s time for a little reality check here: origin-of-life theorists need to explain how a myriad of complex proteins and features arose and self-assembled into a self-replicating life-form by unguided processes, but they are still scraping for mechanisms to explain how an inert primordial soup of organic molecules could have arisen in the first place.
I wish them the best of luck in their efforts, because they’ll need it. They are a long way from explaining how life arose. It looks like Nature was right after all: “How life began is one of nature’s enduring mysteries.”

How did life begin?
Where did life on Earth come from? How did it happen? Those who believe in the Primordial Soup model believe that a nutrient-rich early Earth eventually formed increasingly-complex molecules that gave rise to life. This could have taken place in the deep ocean vents, in clay, or under ice. Different models also give variable levels of importance to the presence of lightning or volcanic activity for the spawn of life. While DNA is the predominant basis for life on Earth now, it has been suggested that RNA could have dominated the first lifeforms. Additionally, other scientists question whether other nucleic acids aside from RNA or DNA may have once existed. Did life spawn just once, or is it possible that is was created, wiped out, and then restarted? Some believe in panspermia, in which microbial life was brought to Earth via meteorites or comets. Even if that is true, it doesn’t answer the question of how that life originated.

How Did Life Begin?
The short answer is we don't really know how life originated on this planet. There have been a variety of experiments that tell us some possible roads, but we remain in substantial ignorance.
