3.5 Billion Years Ago. This is how old fossil stromatolites have been dated. You can find modern versions of these same formations growing now off the coast of Australia.
About 3,500 million years ago.
Archae bacteria. They live in harsh environments and still to this day exist. Photosynthesis came about when an archae bacterium developed a chloroplast, which is what plants use to make energy.
archaebacteria are the type of bacteria which dates back to the first forms of life on earth. And its my guess that bacteria are unicellular whether unicellular or multicellular
There are many statements which are true for bacteria. Bacteria come in various shapes and they consist of a single cell. Bacteria are known to be small in size but very complex in terms of structure.
bacteria
The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. In a laboratoy, bacteria are grown from a solid or liquid material.
Unicellular plants and animals were first forms of life on Earth
bacteria is not right it is prokaryotes
Archeo-bacteria
The first organized form of life is a tiny protozoa.
yes it was bacteria
Bacteria play a crucial role in various ecosystems by cycling nutrients, decomposing organic matter, and maintaining soil fertility. Without bacteria, other organisms would struggle to survive due to the lack of nutrient recycling and decomposition processes that bacteria facilitate. This would disrupt the balance of ecosystems and ultimately lead to the decline and extinction of many life forms on Earth.

Answ2. Yes there are life forms in earth. worms, insects and bacteria. In the Antarctic, they have even found life-forms inside what appears to be solid rock.
they were probably the first multicelluar life- forms

There is more bacteria than other forms of life.
the were archbacteria they were the simplest bacteria and didn't use oxygen
Life came from bacteria that is in a humans body . That is where life came from first
