|The molecular structure of RNA, molecular formula [C10H16O13N5P2]N, comprised a base, a ribose unit, and a phosphate group.|
See also: Defunct theory of life; Carbon-based life; Non-lifeIn 1967, Carl Woese hypothesized that RNA might be catalytic and suggested that the earliest forms of life, described as “self-replicating molecules”, could have relied on RNA both to carry genetic information and to catalyze biochemical reactions—an RNA world.

C10H16O13N5P2 | NOT alive?which led to the formation of DNA, aka the "secret of life" and or first "living molecule":
Excerpt from Libb Thims' 2007 Human Chemistry, chapter "Molecular Evolution", wherein Thims first began to grapple with the defunct theory of life issue, namely illogical supposition that the first form of life was a small molecular entity such as RNA (a 5-element molecule) or a single-cell bacteria (a 15-element molecule), which leads to the absurd conclusion that the precursor molecules or reactant molecules that went into the synthesis of that first "living molecule" were either sort of alive or a dead molecule or something nonsensical to this effect. 
C10H16O13N5P2 [RNA] + C10H16O13N5P2 [RNA] = DNA | YES alive?
which led, once DNA got enclosed into a cell membrane, to the formation of the first human molecule, 150,000 years ago, according to the out of Africa hypothesis:
ZnE22SiE22CuE21BE21IE20SnE20MnE20SeE20CrE20NiE20MoE19CoE19VE18 | YES alive?
are coupled mechanism processes, occurring in a step-by-step manner, each step governed by the first law (energy conservation) and second law (transformation content increase) of thermodynamics. The formation of RNA is only a drop in the bucket in the "big history" picture of this grand process and to label the second of the first formation of RNA as having some type of grand significance in the big picture scheme of things of the structure and dynamics of the universe is only but an anthropocentric molecular structure retelling of the age-old first life story, as found in various semi-modern chemical forms: Erasmus Darwin’s one living filament (1794), of Johann Goethe’s homunculus (1832), of Alexander Oparin’s coazervate droplet (1931), of Carl Woese’s self-replicating molecule (1971), and so on, in what no doubt will be a story retold, in various regurgitated forms, well into the coming centuries.
