A-biogenesis is the name for the proposed hypothesis that organic chemistry transformed into self-replicating organic chemistry that became the first life form on planet earth, and that at least one such life form evolved into all the different species that we see in the fossil record and in the world today. There are obviously many daunting challenges to this hypothesis becoming an accepted theory of science.
The first obstacle is the fact that we don’t actually know what the first life form on planet earth was. The oldest fossilized remains we can study appear to be of single-celled organisms, but we don’t know if those were actually the oldest life forms on the planet or not. We also don’t know the specific structure or what type of early version of DNA or RNA they may have contained.
Research in this field is ongoing and involves looking at how certain chemical structures can self-replicate under different environments and conditions, how they could have become contained in a membrane like structure and how the first steps of a simple RNA-like self-replicating sequence could have developed to become a proto-cell.
Whether or not the hypothesis of a-biogenesis will become an established theory of science on par with evolution remains to be seen.
Points: The claim that science understands how the first life form on planet earth came into existence and the claim that it is impossible for a life form to come into existence by natural means are both claims made without confirming evidence.
