When did the first life appear on earth?
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.
Who were the first to live on earth?
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.
Who is the 1st person that arrived on earth?
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.
When was the 1st life on earth?
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.
