3.5 to 4 billion years
According to the fossil record, the earliest cells lived about 3.5 billion years ago.
To date, fossil evidence shows that humans existed in the Western Hemisphere as far back as 10,000 BC BCE. There is also evidence of tools that also match the fossil remains.

Microorganisms, such as bacteria and algae, have the most abundant fossil evidence due to their vast numbers and widespread distribution throughout Earth's history. Fossilized microbial mats and stromatolites, for example, provide valuable insights into early life on Earth.
The simplest type of biological cell is the prokaryotic cell, which includes bacteria and archaea. Prokaryotes are characterized by their lack of a nucleus and membrane-bound organelles. They appear early in the fossil record, with evidence dating back over 3.5 billion years, making them some of the oldest known life forms on Earth.
The oldest fossil evidence is from single-celled organisms such as bacteria and archaea. These microorganisms have been found in rocks dating back over 3.5 billion years, providing some of the earliest known evidence of life on Earth.
