The earliest forms of life appeared during the Archean Eon, which began around 4 billion years ago. The first life forms were simple, single-celled organisms known as prokaryotes, such as bacteria and archaea. Evidence suggests that these organisms thrived in various environments, including hydrothermal vents and shallow seas, laying the foundation for more complex life forms to evolve later.
The earliest ones still around are stromatolites, but there were lots of earlier life forms.
Yes. Our DNA has been passed on and changed/modified since the earliest forms of life.

The earliest forms of life were microscopic autotrophs that lived in the great prehistoric oceans. Living under the water protected them from the deadly UV rays from the sun, as at this point Earth had not developed a suitable atmosphere. This is true everywhere but Kansas, where the earliest life forms were Adam and Eve. Zing!
Stromatolites are one of the earliest known life forms; some fossils may date back 3.5 billion years - before Earth had any oxygen in it's atmosphere.

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 earliest life forms on Earth were likely single-celled microorganisms such as bacteria and archaea. These organisms appeared around 3.5 to 4 billion years ago in ancient oceans and are thought to be the ancestors of all life on Earth today.
The earliest life forms on Earth were single-celled microorganisms like bacteria and archaea. These simple organisms emerged around 3.5 to 4 billion years ago in the ancient oceans of the planet. They played a crucial role in shaping the environment and paving the way for more complex life forms to evolve.
