As you requested, here are links to various Clinton administration death information on the Downside Legacy:
On the link you provided, the author offered basically four rebuttals to Hoyles approximation which I paraphrase as follows:
If what Hoyle offered were any more than an approximation I would be concerned about points 2 and 3. Nevertheless, others who approached the same problem Yockey, Rocha, Wolfram etc. - all seem to narrow in on the same issues in particular that since the universe had a beginning, the amount of time available for abiogenesis anywhere is not infinite.
It appears the most popular mechanism to explain it is the theory of autonomous biological self organizating complexity.
That theory however comes with a price for the atheist because it means evolution is not a directionless walk. Moreover, a bootstrap for such a process in an RNA world requires toggling between states which are stable to carry information, and not to be reactive (Rocha).
I dont see how producing precise results is a defense for removing the complexity and ambiguity from calculations. Its been a long time since Chem 101, but I think molecules and amino acids do interact, and to remove that would be like removing the interaction of people from an equation as saying that Free Republic could not have been built by just one person in his short life span, born ignorant of everything.
I havent read the other authors, but if they make the same omission
Im not familiar with #1 the anthropic principle, but I dont think that #4 the absence of information is dependent on world view. If we are evaluating the probability of biogenesis, we dont begin with theological premises. The absence of information is very real.
Also there was a #5 reference to the problem of calculating the probability of a predetermined outcome. The author used the lottery example. Maybe the odds were 15 million to one that a specific creature would have been produced randomly, just like the odds are 15 million to one that a specific individual would win the lottery. But someone always wins.
