Probabilistic calculations make it clear that complex molecules such as proteins and nucleic acids (RNA and DNA) could not ever have been formed by chance independently of each other. Yet evolutionists have to face the even greater problem that all these complex molecules have to coexist simultaneously in order for life to exist at all.
Evolutionary theory is utterly confounded by this requirement. This is a point on which some leading evolutionists have been forced to confession. For instance, Stanley Miller's and Francis Crick's close associate from the University of San Diego California, reputable evolutionist Dr. Leslie Orgel says:
It is extremely improbable that proteins and nucleic acids, both of which are structurally complex, arose spontaneously in the same place at the same time. Yet it also seems impossible to have one without the other. And so, at first glance, one might have to conclude that life could never, in fact, have originated by chemical means.1
The same fact is also admitted by other scientists:

DNA cannot do its work, including forming more DNA, without the help of catalytic proteins, or enzymes. In short, proteins cannot form without DNA, but neither can DNA form without proteins.2

How did the Genetic Code, along with the mechanisms for its translation (ribosomes and RNAmolecules), originate? For the moment, we will have to content ourselves with a sense of wonder and awe, rather than with an answer.3
