   The genetic code is arbitrary, in that any mapping from codon to   
   aminoacyl residue would work. Variant mappings exist in nature, mostly   
   in clades with small genomes (often mitochondria), and have been created   
   experimentally. For more divergent mappings there is the strategy of   
   swapping the mRNA and amino acid binding domains of tRNA.   
      
   But the genetic code is not random (it's more robust against base   
   substitutions than the great majority of possible code) and may be in   
   part physio-chemically determined. There is a hypothesis that originally   
   direct interactions between RNA and amino acids were involved in   
   template directed peptide synthesis, and that these interactions are   
   fossilised in the genetic code.

   No. Creationists sometimes try to argue that science excludes the   
   supernatural as a matter of principle. Passing over the slippery nature   
   of what counts as supernatural, I disagree. The actual restriction is to   
   phenomena which behave, at least statistically, in a regular way, or to   
   put it simply science assumes that "evidence means something", i.e.
