Cells are ever so much more than “integrated circuits.” But, they are integrated circuits! As with integrated circuits in man-made devices, many switches must be set in concert and in the right sequence to compute sophisticated function.
Life depends on far more incredibly complex integration of many different kinds of configurable switch-settings than any man-made device.
Not only does each switch have to be set a certain way individually, but all of the switch-settings have to cooperate in computing life’s processes.
One wrong switch-setting can fatally arrest life’s processes.
Life is a concert of activity performed by many diverse subcellular instruments, devices, and nanocomputers. The slightest malfunction can be fatal to life.
How did life’s symphony get written before it was ever performed?
How could each and every instrument in the orchestra show up and each perform its respective part with such purpose and harmony with all the other independent instruments?
How did that symphony get conducted with such finesse right from the start? Not by “chance and necessity.” Not by mere mass and energy interactions.
Life is an all-or-none process. Life cannot “come to life” piecemeal, a little at a time.
Control and regulation are essential to every aspect of life. But control and regulation are formal functions, not just physicochemical reactions. Physicality cannot “do” purposeful, goal-oriented, abstract, conceptual formalisms.
In a purely physical, inanimate world, how could such finely-tuned formal controls and regulation have come into existence? Not even a protocell could arise out of mere chance and necessity. Neither chance nor physical laws can organize anything.
