a) your calculation is irrelevant because no one is talking about a 300 amino acid long protein.
Excuse me, but that was the very topic of the article presented.
very short polypeptides have already enzymatic activity.
Your point?
b) there are transitional forms. take archeopterix as the most prominent example. there are many many others. however transitional forms are of course rare since species stay in more or less the same form for most of their existence. transitional forms gain importance only if environmental changes occur that allow the adaptaion to a new niche.
If evolution were true, there would be BILLIONS of transitions in the fossil record. There would be species NOW in the transitional MODE. Both are NOT TRUE.
c) if you would have a scientific mind then you would try to come up with an alternative scientific explaination instead of refering to God who somehow and miracously put everything here (despite a gigantic pile of evidence against that idea)
Why sidestep the truth? Again, more claims of EVIDENCE and facts wirth NONE presented. Staus Quo.
d) just on the side: biological evolution does NOT depend on how the first cell formed.
It surely does, because without that first cell, there is NO LIFE AT ALL.
e) here is an abstract from a rather new review about peptide formation:

Considering the state-of-the-art views of the geochemical conditions of the primitive earth, it seems most likely that peptides were produced ahead of all other oligomer precursors of biomolecules. Among all the reactions proposed so far for the formation of peptides under primordial earth conditions, the salt-induced peptide formation reaction in connection with adsorption processes on clay minerals would appear to be the simplest and most universal mechanism known to date. The properties of this reaction greatly favor the formation of biologically relevant peptides within a wide variation of environmental conditions such as temperature, pH, and the presence of inorganic compounds. The reaction-inherent preferences of certain peptide linkages make the argument of 'statistical impossibility' of the evolutionary formation of the 'right' peptides and proteins rather insignificant. Indeed, the fact that these sequences are reflected in the preferential sequences of membrane proteins of archaebacteria and prokaryonta distinctly indicates the relevance of this reaction for chemical peptide evolution. On the basis of these results and the recent findings of self-replicating peptides, some ideas have been developed as to the first steps leading to life on earth.
How in the hell does a salt induced peptide formation undermine the statistical impossibility of evolution using the RIGHT peptides and proteins? It doesn't.
