I am reading an old (1981) science-for-dummies book, The Enchanted Loom, subtitle Mind in the Universe, by Robert Jastrow. Old because much of the book is on the similarities between computers at the time and our brain's electrical wiring. A good deal of the book has to do with how brain's on Earth evolved over billions of years, and hence on Darwinian evolution. The book may be outdated, I am not a scientist. It is certainly not state-of-the-art unless that art has not evolved since Phil Collins released In the Air Tonight.
Rational Darwin Doubters, a tiny minority, can do worse, and little better, than to hold up this image:
"That does seem a tough pull", to self, out loud.
To dull Creationists like Trump supporters, it is an impossible pull since no one has ever seen a mole transform into a horse, or a whale.
Jastrow:
My own views on this question remain agnostic, and close to those of Darwin. The theory of evolution seems complete, it seems to require no forces beyond the forces known to science. ...
Pause: Another term for this is a "closed system." By either term the theory requires no outside intervention, i.e. a Creator. Unpause.
...Yet, when you study the history of life, and step back to look at this long history with the perspective of several hundred million years, you see a flow and a direction in it--from the simple to the complex, from lower forms to higher, and always towards greater intelligence--and you wonder: Can this history of events leading to man, with its clear direction, yet be undirected?
Jastrow would have had no way of knowing in 1981 that in 2004 Matthew Cook would prove that an elementary cellular, like in biology, automation known as Rule 110 was "Turing complete", i.e. capable of the computing power of the most powerful machines, like computers or brains.
It can be done; it was proved that it could be done with enough repetitions (years in evolutionary science) of dully, simplistic rules of action. However. Rule 110 had a Creator, Stephen Wolfram first thought it up, Cook created the conditions on a computer and ran the rules of action proving the universality of Rule 110.
But. Rule 110 was one of 256 of Wolfram's Rules. How is it that life on Earth got the only Rule that resulted "always towards greater intelligence" ? Simplistically, that sounds vanishingly unlikely; actually it sounds to my simplistic brain impossible.
Could there have been a Creator who set Rule 110 to work on Earth (and nowhere else) and just let the thing "evolve"? Staunch Darwinians have their own simplistic retort to that: "Yeah, well then who created God?"
