If you’ve ever had the sad misfortune of going out late on a Saturday night in the town I live in, or had the sad misfortune of being governed by the morons people in this part of the world in their infinite wisdom elect, you would know how bad man can muck it up!
Personally I think it’s evidence of de-evolution, and there are some people moving backwards. So much so some have even lost the ability to speak in a language that can be recognized a human, and have lost the cognitive ability to work out for themselves they can walk around a stationary object rather than stare at it, hoping it will move of it’s own accord. I would also say man does have the arrogance to muck things up so badly God has to intervene.
The Bible is full of examples of time God intervenes and times He chooses not to. We don’t know why God sometimes chooses to intervene, and sometimes chooses not to. Unless your a Calvinist. In which case you would say our fallen world and all the bad things that happen in it are part of God great plan and He means it all to happen. In addition, God nudges us all the time in many ways. Who’s to say he does not nudge the physical world? It is, after all, His creation.
I agree with you that DNA is the physical/biological means by which information is transmitted. The extent to which God micro-manages that in terms of creation of new life, and environmental change among other things, is anybodies guess. I like the way you use term ‘God breathed’ as it echoes the great literary imagery of Genesis. However, as God does not have breath in the human sense, the physical mechanism by which God created life is unknown to us.
