Early embryology; glial cell guidance (Introduction)

dhw: […] I agree that such complexities are the best arguments for your God. If he does exist, the question whether he preprogrammed them all 3.8 billion years ago, personally dabbled them, or created a mechanism enabling organisms to work out their own developments remains wide open.

DAVID: 'Wide open" only for you. Giving organisms mechanisms for their own development present the same problems of complexity that have you recognize the 'best arguments' for God. Why have Him give a 'mechanism' which is second-hand design? If He could do that why not directly do it firsthand? Makes a lot more sense.

dhw: Why second-hand? Do you regard the human design of computers, spaceships, literature, music etc. as second-hand? According to you, your God created the human brain which is autonomously capable of complex design. But you insist that he could not possibly have created a mechanism enabling other organisms to make innovative changes to their own bodies (although they ARE capable of autonomously making minor adaptations). Why does your God’s personal design of every single innovation, lifestyle and natural wonder that ever existed make more sense than him designing a mechanism enabling them to do their own designing?

DAVID: But besides God's abilities, there is no other obvious way to explain embryologic development. Chance? Never. Your suggestion?

dhw: I keep telling you my suggestion! And it is not chance.

Your inventive mechanism proposal would need a human-brain-like ability as you describe above. That implies all the complexity of our brain, not found in current studies of the genome. Why do you constantly slough aside the point that development of complex changes, as seen in the gaps in evolution, require foresight of the future needs in order to start designing the plans for those changes? God gave us the brain to do that so the designs are not His second-hand. I'm convinced your nebulous hypothesis is just that in our theistic-mode discussion. How do you explain evolution without God present?
