I am fascinated by Einstein’s quote that the most unbelievable aspect of the universe was that it was intelligible. So my question is does anyone know whether it is so unlikely as to be absurd to suppose that random unguided processes could produce a rational brain in man in as little as 3 billion years. So that our rational brain can understand patterns, order and rules in a Universe that was also produced by random unguided processes? I know the story of monkeys pounding on keyboards for an infinite amount of time will produce all of Shakespeare works, but that is just a fact based on the special case of infinity. As our Universe has a beginning we can’t get away with arguing, given enough time anything could happen, including the evolution of order and intelligibility from randomness. Have computer models been built that take random inputs and yield rational outputs?
