Deflect much? I was not posting at the time. I did read some of

You fantasy about what people believe is tired and unevidenced.
You presume this exaptor of the gaps, and repeat your assertion,
convincing yourself and probably nobody else. Meanwhile, the
implied model in your comment remains foolish. It does not matter
who you address it to, it is simply foolish.

Your fantasy assertion that you "fought to a draw" is unreliable.
You were defeated, repeatedly in what I saw. Creating a protein ribosome
is a fools errand. Why? It probably could be done buy why do it?
The major players to be handled are RNA molecules and ribozymes are
probably better candidates for that job. There are many ribozymes
that remain in cells and they generally manipulate RNA or DNA.
You don't understand this but you pretend to be able to comment on
what to expect. You are foolish because you fail to grasp the
consequences of your ignorance.

If you think that a primitive genetic code of 4 amino acids was
coding for enzymes, then your foolishness is expanded.

Your doubts are irrelevant. You were provided references. You
claim to care but did not follow up on them.

You did. The model implied by your 4^200 is exactly that.

You don't know and yet you pontificate. Foolish.
You were recently provided with an excellent set of references
by Howard that answer the question. You would rather post
garbage than read. Fools like you are not worth the time.

Another foolish comment. Peptides increasing the conformational
specificity of RNA folding is not hypothetical. And the model is
takeover by the peptidyl ribozyme, with more and more peptide
and less and less RNA, not substitution for an independent
entity. And the obvious reason for this is because polypeptides
are better at interacting with small molecules like amino acids.
Meanwhile things like the ribosome remain RNA because they mostly
deal with RNA. The actual condensation reaction of the ribosome
is not the challenge, the specifity of the tRNA to mRNA matching
is. That's distinct from the activation of tRNAs where the chemical
challenges are very different. You have no instinct for this.
And yet you continue to pontificate about it. Foolish.

Why would they? Biochemists are generally not as deluded as
is Behe. He is a special sort of polemicist. He makes obvious
things seem complicated and fools people like you. He has an
axe to grind. Meanwhile, the experiments required to run from
a ribozyme to a full enzyme would take many years with uncertain
success. You would have to really dislike the grad student or
post-doc that you saddled with such a project. They could easily
spend many years on it and not get a publishable result.
And even if they did, what's the practical value? There are
far more useful things for talented scientists to be doing.
Reproving the Earth is not flat, or that the Earth circles the
Sun is a poor use of a geologists or an astrophysicists time.
The same is true of addressing ID apologists.

If you were serious, and if you cared, you would put in
the effort and find the references. You would spend more
effort reading them than in otherwise worthless banter.
Unless you redeem yourself by finding them and finding
the models I cite, you are not worth my time.
