I believe I am the first human being to have asked this question.
So I googled it, no results, which is funny.
There are other theories about origin of life and the exact problem I
mentioned "current origin of life theories require a too complex lifeform as
starting point".
My search on google produced this interesting link, which might indicate
that so far researchers might be barking up the wrong tree.
Perhaps a simple alan turing computer capable of attracting molecules might
explain how more complex life forms/sequences came to be.
A simple computer which simple increments a counter which in turn attract a
certain sequence of molecules/chemicals/matter might already be enough to
create life eventually.
As a sort of "search computer", which simply plows through all possible
combinations by brute force ! ;) :) HAHA !
Anyway here is the somewhat interesting link and story, how "science" is
struggling to come up with a simple machine capable of constructing and
evolving life ! ;) :)
(At the bottom of this posting I give further pointers for further research
which should be obvious by now after these few postings of me, but kinda
spell it out just one more time to let you know what I would love to see !
;) :))

A new study published in Proceedings of National Academy of Sciences rejects
the theory that the origin of life stems from a system of self-catalytic
molecules capable of experiencing Darwinian evolution without the need of
RNA or DNA and their replication.
The research, which was carried out with the participation of Mauro Santos,
researcher of the Department of Genetics and Microbiology at Universitat
Autònoma de Barcelona (UAB), has demonstrated that, through the analysis of
what some researchers name "compound genomes," these chemical networks
cannot be considered evolutionary units because they lose properties which
are essential for evolution when they reach a critical size and greater
level of complexity.
The U.S. National Aeronautics and Space Administration (NASA) defines life
as a "self-sustaining chemical system capable of Darwinian evolution." The
scientific theories on the origin of life revolve around two main ideas: one
focuses on genetics -- with RNA or DNA replication as an essential condition
for Darwinian evolution to take place -- and the other focuses on
metabolism. It is clear that both situations must have begun with simple
organic molecules formed by prebiotic processes, as was demonstrated by the
Miller-Urey experiment (in which organic molecules were created from
inorganic substances). The point in which these two theories differ is that
the replication of RNA or DNA molecules is a far too complex process which
requires a correct combination of monomers within the polymers to produce a
molecular chain resulting from the replication.
Until now no plausible chemical explanation exists for how these processes
occured. In addition, defenders of the second theory argue that the
processes needed for evolution to take place depend on primordial
metabolism. This metabolism is believed to be a type of chemical network
entailing a high degree of mutual catalysis between its components which, in
turn, eventually allows for adaptation and evolution without any molecular
replication.
In the first half of the 20th century, Alexander Oparin established the
"Metabolism First" hypothesis to explain the origin of life, thus
strengthening the primary role of cells as small drops of coacervates
(evolutionary precursors of the first prokaryote cells). Dr Oparin did not
refer to RNA or DNA molecules since at that time it was not clear just how
important the role of these molecules was in living organisms. However he
did form a solid base for the idea of self-replication as a collective
property of molecular compounds.
Science more recently demonstrated that sets of chemical components store
information about their composition which can be duplicated and transmitted
to their descendents. This has led to their being named "compound genomes"
or composomes. In other words, heredity does not require information in
order to be stored in RNA or DNA molecules. These "compound genomes"
apparently fulfil the conditions required to be considered evolutionary
units, which suggests a pathway from pre-Darwinian dynamics to a minimum
protocell.
Researchers in this study nevertheless reveal that these systems are
incapable of undergoing a Darwinian evolution. For the first time a rigorous
analysis was carried out to study the supposed evolution of these molecular
networks using a combination of numerical and analytical simulations and
network analysis approximations. Their research demonstrated that the
dynamics of molecular compound populations which divide after having reached
a critical size do not evolve, since during this process the compounds lose
properties which are essential for Darwinian evolution.
Researchers concluded that this fundamental limitation of "compound genomes"
should lead to caution towards theories that set metabolism first as the
origin as life, even though former metabolic systems could have offered a
stable habitat in which primitive polymers such as RNA could have evolved.
Researchers state that different prebiotic Earth scenarios can be
considered. However, the basic property of life as a system capable of
undergoing Darwinian evolution began when genetic information was finally
stored and transmitted such as occurs in nucleotide polymers (RNA and DNA).

Perhaps my postings might persuade them to investigate a different approach
or a mixed approach:
1. Try to construct some kind of computer by chance/random process which is
then in turn capable of attracting these kinds of chemicals/compounds etc,
to see if that might eventually create some kind of successfull lifeform.
2. Ofcourse it could also be tried in some kind of super computer simulation
to speed up the entire process of evaluating the real possibility of this !
;)
Personally I would first like to see somebody construct a computer which can
transfer an electrical sequence/computer program onto
chemicals/matter/compounds at a very simple level. Just to proof that it can
be done/it's possible and that would give the hypothesis/theory merrit/a
serious contender for origin of life ! ;) :)
