in the beginning when God created it
Life is believed to have first appeared in Earth's oceans around 3.5 billion years ago. This was in the form of single-celled organisms like bacteria and archaea. These early life forms were the foundation for all subsequent life on Earth.
The most primitive life on Earth are single-celled organisms such as bacteria and archaea. These organisms have simple cell structures and are thought to have been some of the first life forms to appear on Earth billions of years ago.
The first species to appear on Earth were likely single-celled microorganisms such as bacteria and archaea, which emerged around 3.5 billion years ago. These simple life forms were the earliest pioneers on our planet, laying the foundation for the complex biodiversity we see today.
Bacteria are believed to have first appeared on Earth over 3.5 billion years ago during the Archean Eon. These simple single-celled organisms are among the earliest forms of life on our planet.
The first known species to appear on Earth were single-celled microorganisms like bacteria and archaea. These simple life forms emerged around 3.5 billion years ago.
Scientists think that the first life forms appeared on Earth about 3.6 billion years ago. These were simple cells that eventually evolved into the abundance of life we see today.

Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
yes
Air breathing life appeared on earth about 400 million years ago, a little bit after the first plants came. The first air to be breathed was by insects.
Scientific AnswerThe first bacterial life to appear on Earth was 3.46 billion years ago in the Precambian supereon. The first complex life appeared around 600 million years ago just preceding the Cambrian Explosion of life 530 million years ago.
Chick or the egg!
In someones pants??
Life first appeared on Earth around 3.5 billion years ago through a process called abiogenesis, where simple organic molecules combined to form more complex molecules that eventually led to the development of living organisms.
well the first thing was algae...and formed from there on
Stromatolites first appeared on Earth around 3.5 billion years ago. These structures are formed by the activity of microbial communities, primarily cyanobacteria, and are some of the earliest known evidence of life on our planet.
