Natures wonders: squid eye lens focuses exactly (Introduction)

dhw: I challenged your claim that God’s sole purpose was the production of the human brain, which does not fit in with the higgledy-piggledy bush of evolution. You replied that the bush “provides the balance of nature for life to continue”. That is a complete non sequitur, as I have pointed out. And so you change the subject! Your anthropocentric interpretation of your God’s purpose does not fit in with the history of life.

DAVID: Of course it does. See below. The human brain is the pinnacle of your 'improvement' and my 'complexity' theories.

Whether the human brain is the “pinnacle” or not is open to debate, as it depends on your criteria for such a judgement, but that is not the issue. I am happy to agree that in terms of intelligence and technology, we are the tops (so far). But you could have had that with a divine dabble. It still doesn’t explain why God designed eight stages of whale, the monarch’s lifestyle and the weaverbird’s nest in order to produce us. And your “balance of nature” does not provide a link or a reason, since it applies to ALL forms of life. As for “see below”, this is what is below:

dhw: ….Since bacteria survived, it’s not just the human brain that requires explanation. Bacteria as you keep reminding me don’t have brains, so we have to explain EVERY brain and every other innovation that led to humans, dinosaurs, whales and the duck-billed platypus. We agree that there has to be a drive for improvement (me), complexity (you). The drive may have been initiated by your God, if he exists, but in terms of the history of evolution, I suggest that it is built into and implemented by organisms themselves, whereas you believe that every innovation was preprogrammed 3.8 billion years ago or personally dabbled by your God. I think we’ve been here before.

David: Of course everything requires explanation. Mine is simple, God.

You have not explained how God's need to design eight stages of whale etc.etc. in order to produce the human brain fits in with the history of life. Keeping life going does not make the human brain the sole purpose, since life kept going and will no doubt continue to keep going with or without the human brain.
