“....Even a very beneficial gene spread very slowly or not at all if it was in an individual whose overall genetic makeup was much less fit than the average.....”
This assertion is erroneous: how slow is “very slow” and in what context?
There are plenty of examples of beneficial genes (beneficial to the individual that has them) that have spread over most of a population in just a few decades -I would not describe that as “very slow” by any stretch of the imagination. Just two examples; the spread of the genes for DDT resistance in mosquitoes; the spread of genes for antibiotic resistance in bacteria. -both occurred within just a few decades.
“...Conversely, an inferior gene can become prominent in the population if it is in an individual whose overall genetic makeup is far superior to the norm....”
That would be correct for THAT individual; but then gene reshuffling and a few mutations later and there would be plenty of genetic variants that have that disadvantageous gene and no genetic advantage to compensate (so will be selected out) and there would be genetic variants that do NOT have that disadvantageous gene and and also will have other genetic advantages (so will be selected ) .
The content of the rest of that paragraph and the following four paragraphs about the probabilities is just a load of crap because it ignores the two points above.
“...The probability of vertebrate evolution starting from the Big Bang is ….”
Vertebrate evolution did not start at the big bang and nobody claims it did.
The big bang is NOT a theory of vertebrate evolution.
“...only a few hundred extra-solar planets have been detected so far. Since it becomes more difficult to detect a planet the further from the earth it is, we can safely conclude that there is no way that even an insignificant fraction of 1030,000 evolution-supporting planets will be detected within the next few decades....”
-and given the size of the universe, the estimate for the number of earth-like planets (rocky planets within the inhabitable zone with liquid water) is well over a billion -even within just our galaxy!

“...There could be one hundred billion Earth-like planets in our galaxy...”
The content of the rest of your post is crap because it ignores this above point.
