Well, In my opinion, I think that e. coli is long living

Cyanobacteria or blue-algae are microbes that produce oxygen through the process of photosynthesis. Some scientists believe that these bacteria were the first to produce oxygen on Earth.
Archaeologists. Astronomers. Biologists. Chemists. Computer Scientists. Earth Scientists. Educational psychologists.
Any scientists interested in earth sciences: mineralogist and mining engineer.
An Earth scientists can study a number of things. Volcanology, geology and environmental Biology are a few examples of Earth sciences.
God created it along with everything else in the universe. The scientific would be that they developed from single-celled organisms; some scientists even believe that some bacteria may have arrived from space. No one really knows for sure, though simple life has been created in the laboratory by the introduction of electricity (such as a lightning bolt might provide) to a chemical "stew" similar to what is presumed to have existed early in this planet's history. Sound science does not necessarily preclude the existence of a "Creator", but we can be absolutely sure that Genesis, and other creation stories, are nothing more than attempts by early humans to explain existence, and are not factual blow-by-blow accounts.

Bacteria are usually considered as one of the pioneering generations of life on earth by the scientists.
bacteria
Simple single-celled organisms such as bacteria and archaea are believed to have originated during the primordial period. These early life forms were likely anaerobic and thrived in the harsh conditions of the early Earth.
simple organic molecules
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.
It's simple, when the plates collide, the crust of the earth wrinkles forming mountains.
We have fossils, so to speak, in rocks that are about 3.5 billion years old. Some form of simple prokayote in filamentous strings. Impressions left in sedimentary rock.' Still there must have been life before this, but the evidence is implied genetics and not all that firm. Possible a form of replicator; simple genetic replication.
Normally this would come under biology, However many bacteria are involved in geological processes (e.g. stromatolites) and it has been found that bacteria live deep down in the rocks of the planet. Thus were bacteria are involved in this way their study would be of concern to the earth scientists too.
Bacteria CAN live on Earth.
Many scientists think that the moon was originated when a large meteor hit the Earth, knocking a chunk off of it. The chunk most likely came from somewhere within the current Pacific Ocean.
