Quote from futurecurrents:
I know what your saying. However it's true there were a vast number of breeder sites over vast periods of time with vast numbers of chemicals involved. It's this huge number of trials and error, and building-upon, that lead to life.
My initial and main point remains true, and that is that protobiologists do NOT say that life could not have come from chance. Almost all of them believe it did. The initial premise of that argument is false.
I will admit there is a slim possibility that earth was seeded with bacteria from comets. But if it was, that bacteria evolved on another planet through similar processes.
Can you read...
the paper presented you the conclusions of nobel prize winners and the giants of the field. They tell you that although it could not have happened by chance.... we are here.
According to Crick âthe origin of life appears at the moment to be almost a
miracle, so many are the conditions which would have had to been satisfied
to get it goingâ (1981: 88); the emergence of life was nevertheless a âhappy
accidentâ (p. 14).

According to Mayr, âa full realization of the near impossibility of an origin of life brings home the point of how improbable this
event was.â (1982: 45). Monod famously claimed that although the probability of life arising by chance was âvirtually zero. . .our number came up in the
Monte Carlo gameâ (1974: 137). Life, as Monod puts it, is âchance caught
on a wingâ (p. 78). That is, although natural selection took over early to produce the diversity of life, its origin was nothing but an incredibly improbable
fluke.Does Origins of Life Research Rest on a Mistake? 459
However, the vast majority of experts in the field clearly define their work
in opposition to this view. The more common attitude is summed up neatly
by J. D. Bernal.
[T]he question, could life have originated by a chance occurrence of atoms,
clearly leads to a negative answer. This answer, combined with the knowledge
that life is actually here, leads to the conclusion that some sequences other than
chance occurrences must have led to the appearances of life. (quoted in Fry 2000:
153)
Having calculated the staggering improbability of lifeâs emergence by chance,
Manfred Eigen (1992) concludes,
The genes found today cannot have arisen randomly, as it were by the throw of
a dice. There must exist a process of optimization that works toward functional
efficiency. Even if there are several routes to optimal efficiency, mere trial and
error cannotbe one of them. (p. 11)
It is from this conclusion that Eigen motivates his search for a physical principle that does not leave the emergence of life up to blind chance, hence
making itreproducible in principle:
The physical principle that we are looking for should be in a position to explain
the complexity typical of the phenomena of life at the level of molecular structures and syntheses. It should show how such complex molecular arrangements
are able to form reproducibly in Nature. (p. 11)
According to Christian de Duve (1991),
. . .unless one adopts a creationist view,. . .life arose through the succession of an
enormous number of small steps, almost each of which, given the condition at
the time had a very high probability of happening. . .the alternative amounts to
a miracle. . .were [the emergence of life] not an obligatory manifestation of the
combinatorial properties of matter, it could not possibly have arisen naturally.
