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.

The earliest lifeforms on Earth were likely single-celled organisms, such as bacteria and archaea. These organisms were simple in structure and relied on primitive forms of metabolism to survive. Over time, they evolved into more complex life forms.
Earth is the planet with the most life forms.
Unicellular plants and animals were first forms of life on Earth
The earliest forms of life likely used anaerobic respiration, which does not require oxygen to produce energy. This process is less efficient than aerobic respiration but can still generate ATP for cellular processes.
The earliest ones still around are stromatolites, but there were lots of earlier life forms.
Cyanobacteria

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!
By creating the crust
the were archbacteria they were the simplest bacteria and didn't use oxygen
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.

The prevailing theory of the origin of life on earth posits that it began in the oceans.
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.
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.
