Even if life really did evolve on earth or anywhere it is virtually impossible that it can ever become a theory because it is virtually impossible any evidence could survive anywhere. If it is ever shown that life blew in on the cosmic wind even this would have no bearing on the "theory" of abiogenesis. That life could have arisen naturally through natural processes is more akin to a belief than an hypothesis; an attractive belief but a belief nonetheless.
Abiogenesis and Evolution are two different fields of studies.
Abiogenesis is still a hypothesis.
Evolution is a scientific theory.
Evolution is about biodiversity of life (eg adaption, speciation, etc), and the mechanisms that drive the change (eg Mutations, Genetic Drift, Natural Selection, etc).
Abiogenesis is about chemistry and biochemistry, and about the origins of essential biological macromolecules (eg amino acids and the proteins, nucleic acids, carbohydrates, lipids (fatty acids), etc), BEFORE living cells exist about 3.6 billion years ago.
And no matter how many times I have to explain the differences between these two, you keep repeating the same silly mistakes, over and over again.
Beside.
You don’t need to know what the first life is to understand Evolution, because Evolution is about the diversity of life, not the origin of the earliest life.
If you study biology at all, you would know that most studies are only of extant species, not of ancient and primitive life.
Most biology students never touch on paleontology subject - the study of fossils. Paleontology is specialized subject/course, that majority of students never require to learn.
Students can still learn biology without ever touching a fossil of animals or plants.
Biologists can study extant species, not just by comparing morphology of animals or plants; no, biologists can learn about Evolution more frequently they have been studying species of their respective DNA - eg the mitochondrial DNA (mtDNA) in animals, and chloroplast DNA (cpDNA) in land plants and some families of algae (eg green algae, red algae).
The use of mtDNA testing and comparison allow for how closely related one species or subspecies to the other, as well as provide estimated time or period of the last common ancestor.
