If our senses are correct, there seems to be only two possibilities as to how they came to be correct:
- Intelligence created them that way
- They came to be so ultimately by chance
I see no reason to believe that no. 2 is correct, because says that a single state was picked by chance out of huge numbers of other equally likely possibilities. For example, we could interpret some aspects of reality correctly, but not others. When you consider how many aspects of reality there are the number of combinations become enourmous. If I believe in no. 2, then I must assume that this one state out of huge numbers of equally likely states is true. I see no basis for this assumption, since nothing increases the likelihood of this one state being the truth.
No. 1 though provides a reason for this one state out of huge numbers of equally likely states to be selected-the intelligence wanted to.
So what you’re really talking about, if you don’t notice it, is Intelligent Design. I’m not sure what you mean by aspects of reality and possible states. Are you talking about the laws of the universe? If so then you’re talking about the fine-tuned argument for intelligent design. I don’t know much about fine tuning, but we’ve been talking about the ability to interpret reality which I believe can and has come about by natural processes.
You’re under the impression that evolution by natural selection is random, which is not the case. Mutations in DNA for the most part seem random becuase they come about through mistakes while copying the huge molecules. Those mutations are read by RNA and cause the final traits of the organism being built to be different than before, or evolve. These mutations can be benefitial, harmful, or have no effect at all on the organism. Oftentimes for a trait to change, it takes several mutations. But when there has been enough mutations to develope biological changes, the new organism is tested against its environment. This is where the process of evolution becomes totally selective, and not random at all.
Earliest fossils of life are dated back to almost 3.5 billion years old. About 530 million years ago, the fossil record shows a large proliferation of the existence of complex multicellular organisms. This age was dubbed the Cambrian explosion. Since then these millions of multicellular organisms had millions of years to evolve into greater complexity. We have fossils of many very different animals than we have today which we know have gone extinct for various reasons. All organisms who had lived in the past hundred thousand years or so while man has been around had ancestors whose DNA made them very successful in their environment, while thousand times more organisms have been outcompeted with since the cambrian era and have gone extinct. It’s estimated 99% of all the species who ever lived have produced dead end evolutionary lines.
So, interpreting reality. Obviously those organisms who had been able to interpret reality better than the others had one advantage over them. It is believed that just before or during the beginning of the Cambrian era, the very first primitive eye had devoloped. It of course was not very complicated, but the race between predators and prey to develope better eyes was on. Those who were better able to interpret reality, survived.
Nowadays there are different eyes which do not function the same way. Different animals can focus better, can see various wavelengths of light (We humans can only see the “visible” spectrum of light, but other animals can see x-rays like certain birds and insects like bees). Also us humans don’t have the best possible version of the eye. We have a distinct blind spot which other eyes don’t have.
The eye used to be a great topic for intelligent design and creationism proponents because no one thought that such a complex organ could have evolved becuase it depended on such an intricate assemblage of parts that it had to all be formed at once. But we have detailed explanations of how the eye has developed.
