I odn't think that there is any quantum element to the mind. Penrose's speculations are interesting but have serious problems. For instance microtubules are an ordinary part of eukaryotic cells and to the best of my knowledge those in the brain are nothing special.
I'm not familiar with the holographic principle so I won't comment on that.
But to calculate the probability of life forming - not life with human level intelligence really would have to KNOW what sort of conditions ARE "just right". And to do that we'd have to know the possible forms of life (we can't just say that it has to be just like the life we know about. A recent popular level book - Jack Cohen and Ian Stewart's _What Would a Martian Look Like_ aka _Evolving the Alien_ goes into the issues.
Now the real question is why - when I am pointing out that your argument is based on very qustionable assumptions you suddenly want to claim that I am being hostile to the conclusion ? Isn't it you that is being hostile to the possiblity that life could form naturally ?
