The earth was a messy place to start with, but the early conditions may have been messier than how it was previously described. New studies, however, claims that life may have been born out of this mess as well. That said, understanding life mean going through the mess and recognizing

To create life, three components are crucial to the building blocks of any living organism. They are RNA, DNA, and the engineer of all life structure is the genetic code that holds the blueprint for all living things. It can be assumed that cell had the three-component to create all the flora and fauna and arm them with the tools needed for natural selection and evolving to the top rung in earth's habitat.

 Initially, the RNA and DNA were singular partners, no pairing like in more evolved cells. One theory puts forward that RNA has the ability to reproduce without any pair, unlike DNA. The "RNA World" hypothesis provides the answer for now, until something comes along. Studies made show that the nucleotides (A, C, G and U) were form in the primordial soup earlier than expected by scientists. Considering the conditions of the primordial soup, this could have been a rollercoaster ride.

Jack Szostak, a Nobel Prize Laureate and other scientists suggested a model that takes into account how RNA was created in the primitive past. One keynote in the model is that it was like Dr Frankenstein's lab, everything is complete, and utter disarray but the chaos formed RNA with a longshot chance.  When RNA formed but this chance, other chemicals were made from arabino-deoxy-and ribonucleotides (ANA, DNA, and RNA).

 For all intents and purposes, getting RNA from primordial matter is just pure luck as the variables in gathering and forming chemical compounds do not always happen. The "RNA World" hypothesis explains that chance is the main factor, no one really knows the mechanics of life formation too. All there are just guesses based on facts and studies.

 Nothing is definite when the primordial soup in a primitive melting pot, operating by random numbers. Before, the RNA all organisms have now, there were flops and reboots of it. Just like Frankenstein's monster, other proto-RNA must be so alien to the perfected RNA keeping everything alive.

The RNA  developed from failures is homogeneous compared to earlier heterogeneous versions of it. Pure RNA is homogeneous and precise, oligonucleotides (like ANA and DNA), boosted the ability for self-replication. It was just the right mix that led to what life is today. 

Developed RNA multiplied faster than other RNA hybrids, it was then the dominant RNA to lead beyond the proto-RNA stage. The developments came fast, and they multiplied in the early tide pools, that led to the first simple organism. Inside the hybrid RNA became what RNA and DNA is today.

The primordial soup was just the medium, and the RNA is the key to life on early earth. Most of the time, RNA is the key chemical getting replicated over other nucleic acids, just like natural selection.
