The only thing wrong with that is that Amino acids will assemble and
fold into biological proteins apart from the specified instructions to
do so that are in DNA, since it is RNA which arranges and bonds the
Amino Acids into chains called Proteins.
RNA occurs naturally when shaking a vile with some other naturally
occurring molecules fool. Plus it's like your saying that it is
possible and not possible in the same argument. There may be an appeal
to ignorance since your implying it cannot happen because we have not
seen it happen yet, but we have seen it.
Most of the higher elements that make up biological cells and hence
our bodies, come from outer space in the form of star dust from stars
that built up the heavier elements...

RNA is made from "naturally_occuring" nucleotides; Molecules composed
of a nitrogen containing base, a 5-carbon sugar, and one or more
phosphate groups. Long strands of nucleotides form nucleic acids (see
above). The sequence of bases in DNA or RNA represents the genetic
(hereditary) information of a living cell.

In the late 1960s Carl R. Woese of the University of Illinois, Francis
Crick, then at the Medical Research Council in England, and I (working
at the Salk Institute for Biological Studies in San Diego)
independently suggested a way out of this difficulty. We proposed that
RNA might well have come first and established what is now called the
RNA world - a world in which RNA catalyzed all the reactions necessary
for a precursor of life's last common ancestor to survive and
replicate. We also posited that RNA could subsequently have developed
the ability to link amino acids together into proteins. This scenario
could have occurred, we noted, if prebiotic RNA had two properties not
evident today: a capacity to replicate without the help of proteins
and an ability to catalyze every step of protein synthesis.
There were a few reasons why we favored RNA over DNA as the originator
of the genetic system, even though DNA is now the main repository of
hereditary information. One consideration was that the ribonucleotides
in RNA are more readily synthesized than are the deoxyribonucleotides
in DNA. Moreover, it was easy to envision ways that DNA could evolve
from RNA and then, being more stable, take over RNA's role as the
guardian of heredity. We suspected that RNA came before proteins in
part because we had difficulty composing any scenario in which
proteins could replicate in the absence of nucleic acids.
During the past 10 years, a fair amount of evidence has lent credence
to the idea that the hypothetical RNA world did exist and lead to the
advent of life based on DNA, RNA and protein. Notably, in 1983 Thomas
R. Cech of the University of Colorado at Boulder and, independently,
Sidney Altman of Yale University discovered the first known ribozymes,
enzymes made of RNA. Until then, proteins were thought to carry out
all catalytic reactions in contemporary organisms. Indeed, the term
"enzyme" is usually reserved for proteins. The first ribozymes
identified could do little more than cut and join preexisting RNA.
Nevertheless, the fact that they behaved like enzymes added weight to
the notion that ancient RNA might also have been catalytic.

RNA world hypothesis From Wikipedia, the free encyclopedia.
RNA world hypothesis states that RNA was, before the emergence of the
first cell, the dominant, and probably the only, form of life. The
phrase "The RNA World" was first used by Walter Gilbert in 1986.
This hypothesis is supported by RNA's ability to participate in the
storage, transmission, and duplication of genetic information,
similarly to DNA, coupled with its ability to act as a ribozyme
(similar to an enzyme), catalyzing certain reactions. From the point
of view of reproduction, molecules exist for two basic purposes: self-
replication and catalysis assisting self-replication. DNA is capable
of self-replication, but only assisted by proteins. Proteins are
excellent catalysts, but fail to catalyze processes complex enough to
recreate themselves, individually. RNA is capable of both catalysis
and self-replication.

Abiogenesis (Greek a-bio-genesis, "non biological origins") is the
formation of life from non-living matter. Today the term is primarily
used to refer to the chemical origin of life, such as from a
'primordial soup' or in the vicinity of hydrothermal vents, and most
probably through a number of intermediate steps, such as non-living
but self-replicating molecules (biopoiesis)...
...In 1936 Aleksandr Ivanovich Oparin, in his "The Origin of Life on
Earth", suggested that organic molecules could be created in an oxygen-
less atmosphere, through the action of sunlight. These molecules, he
suggested, combine in ever-more complex fashion until they are
dissolved into a coacervate droplet. These droplets could then fuse
with other droplets and break apart into two replicas of the original.
This could be viewed as a primitive form of reproduction and
metabolism. Favorable attributes such as increased durability in the
structure would survive more often than nonfavorable attributes.
Around the same time J. B. S. Haldane suggested that the earth's pre-
biotic oceans - very different from their modern counterparts - would
have formed a "hot dilute soup" in which organic compounds, the
building blocks of life, could have formed. This idea was called
biopoiesis or biopoesis, the process of living matter evolving from
self-replicating but nonliving molecules....
...[The] Clay hypothesis (sometimes called clay theory) has been
presented by Graham Cairns-Smith as a possible solution of the problem
of origin of life from inorganic non-living matter. It is based on the
assumption that original living organisms were low-complexity "naked
genes", whose shape and chemical properties influenced their survival
chances; the transition from inorganic lifeforms to DNA-based
organisms was a "genetic takeover".
Cairns-Smith suggests crystals as original naked genes, and in
particular clays. Clays can also include other atoms and molecules in
their structures, and perhaps evolved including more and more complex
structures, until DNA-related molecules would have taken control of
the organism, becoming the genetic driver of its life...

The iron-sulfur world theory is a hypothesis for the origin of life
advanced by Günter Wächtershäuser, a Munich chemist and patent lawyer,
involving forms of iron and sulfur. Wächtershäuser proposes that an
early form of metabolism predated genetics. Metabolism here means a
cycle of chemical reactions that produce energy in a form that can be
harnessed by other processes. The idea is that once a primitive
metabolic cycle was established, it began to produce ever more complex
compounds.
A key idea of the theory is that this early chemistry of life occurred
not in bulk solution in the oceans, but on mineral surfaces (e.g. iron
pyrites) near deep hydrothermal vents. This was an anaerobic, high-
temperature (near 100°C), high-pressure environment. The first 'cells'
would have been lipid bubbles on the mineral surfaces.
Wächtershäuser has hypothesized a special role for acetic acid, a
simple combination of carbon, hydrogen, and oxygen found in vinegar.
Acetic acid is part of the citric acid cycle that is fundamental to
metabolism in cells.
