After much reading and careful pondering I will accept that using 'language' or 'code' when discussing dna is probably not a good thing to do. It opens up a minefield of problems (semantics, types of philosophical arguments) which tend to side track the issue. (I came across a forum which had been debating this very issue for the last three years!!) One thing seems clear to me: the various molecules are doing things in an ‘ordered’ way which then results in a living ‘creature’. Why do these molecules replicate, break off, move in one direction rather than another etc? So I think this might be where the idea of ‘language’ comes from. If I may be permitted to offer a different perspective and ask: do all of these processes just mentioned, which result in producing very complex living beings, suggest an intelligence or plan even, which is ultimately responsible for their existence? I would say yes, they do. I remember when I was still quite young, in my teens and I watched a film animation about the cell. I was amazed at how similar it was to a factory, how all the parts of the cell had their own jobs to do etc. It was as if I had my own eureka moment and realised that the Creator is perceived via the world. That’s me though.
