The link that you gave listed the "reasons" quoted below why all creationist probability calculations are in error.
Sadly for your argument, the math that I gave you made none of those errors.
"Problems with the creationists' "it's so improbable" calculations1) They calculate the probability of the formation of a "modern" protein, or even a complete bacterium with all "modern" proteins, by random events. This is not the abiogenesis theory at all.
2) They assume that there is a fixed number of proteins, with fixed sequences for each protein, that are required for life.
3) They calculate the probability of sequential trials, rather than simultaneous trials.
4) They misunderstand what is meant by a probability calculation.
5) They seriously underestimate the number of functional enzymes/ribozymes present in a group of random sequences."
