The first life on Earth is estimated to have appeared around 3.5 to 4 billion years ago in the form of single-celled organisms. These early life forms evolved into more complex organisms over time.
The first life forms on Earth were single-celled organisms such as bacteria and archaea that appeared around 3.5 billion years ago. These simple life forms evolved into more complex organisms over time.
The first human on Earth is believed to be Homo sapiens, who evolved around 300,000 years ago in Africa. There is no single identifiable first person to have arrived on Earth as humans evolved over time.
The first life on Earth is believed to have originated around 3.5 to 4 billion years ago in the form of single-celled microorganisms. These early life forms evolved over time into more complex organisms, leading to the diverse living species we see today.
A scientist who studies the history of life on Earth is called a paleontologist. They examine fossils and other traces of ancient life to understand how organisms have evolved over time.

The first life forms are believed to have evolved in the oceans around 3.5 billion years ago. This early life consisted of single-celled microorganisms like bacteria and archaea. These organisms evolved and diversified over time, eventually giving rise to more complex life forms.

There is no definitive answer to which country was the first on Earth, as the concept of countries and nations has evolved over time. Historically, ancient civilizations like Mesopotamia or Egypt are among the earliest known organized societies.
Oxygen evolved for first time. Many compounds were oxidised
If you mean how did life start then no one can answer this because no one really knows there are a few possiblities like germs evolved or maybe a metorite crashed into earth which contained life forms but maybe we will find out some time in the future .
Life is believed to have originated on Earth around 3.5 to 4 billion years ago, shortly after the planet formed. The exact timing is difficult to determine due to the scarcity of early fossil evidence.
When humans evolved and realized they were standing on something.
