Not exactly. Microfossils and chemical traces of life were present at least by 2.7 billion years ago. It
is said, with good supporting evidence, that the first organisms on Earth were probably single-celled prokaryotes that were probably genetically similar to the organisms belonging to the domain Archaea. These are prokaryotic microorganisms are genetically distinct from bacteria and often found living in habitats with extreme environmental conditions such as high temperature or salinity (salty). Life was first in the oceans and seas before being found on land.
Well there is a theory out there that says the frist living organism was a Bacteria,and that through evolution it became all the living organiams today. But there is no solid prof.
Answer:
Bacteria were the first life on Earth. They formed from a process of abiogenesis (Link) and evolved into all life presently on earth.
the most possible theory that bacteria made a complex life on earth some of the asteroids that crashed on the earths surface. this theory is proven by scientists that so me of the asteroids that crashed on earth had some bacteria that spread to make the earth habitable
By evolving rapidly into multi-celled organisms .
I don’t know
The earliest lifeforms that were found on Earth, were called prokaryotes. Prokaryotes are groups of organisms without a membrane bound nucleus. They are most commonly seen in the form of bacteria.
Bacteria, the most numerous organisms on Earth , are unicellular organisms - just had this question on a homework
Unicellular- organisms include bacteria, the most numerous organisms on Earth. Multicellular- organisms are composed of many sells and they lie
They were unicellular organisms like bacteria,They respire anaerobically,The are known as the Monera,Their were unicellular,They were prokaryotic, (no well defined nucleus),They moved, using flagella or a cilia.
Bacteria breaks down and converts other living and dead organisms into food. If it werent for bacteria and detritus feeders the earth would be scattered with dead animals and trees
The earliest life forms were mostly different kind of bacteria and plants and other organisms.

ummm.... i think its is the algae and germy bacteria. maybe it iss dino sars?
Prokaryots
Earth's first organisms were the Single- Celled organismsBacteriaFungiAnd Protozoa
Bacteria.
Nobody really knows when the earliest organisms were on Earth. It was definitely more than a million years ago.

if they werent there nothing would live on earth
