> "The probability is next to nil that highly complex molecules like RNA, DNA and proteins got created spontaneously through purely random or chance processes. However, the nearly-impossible became possible, i.e. the unlikely set of events became likely, through the mechanism of autocatalysis.Supply of free energy, of course, was/is the prerequisite for all this to become possible.'-None of this is wrong, all possible. Autocatalytic molecules are rare.-

The miracle of evolution." Sharon Moalem-I just 'love' statements as optimistic as "had established itself", positive past tense, conveying 'it must have happened', rather than "extreme faith" that it happened.
