What’s so special about eyes? Here are some facts about a human one specifically:
- Your eyeball is specially protected by being in a socket and as a result only about 1/6th of the eye is exposed.
- It is said that eyebrows prevent sweat from going into the eyes and the lashes keep dirt away.
- They heal very quickly!
- We have over 1 million nerve fibers connecting an eye to the brain, and as a result of its complexity, a complete eye transplant has not been done yet.
- An iris has 256 unique characteristics compared to a fingerprint’s 40!
- It takes the brain 1/10th of a second to process vision!
- We can see about 10 million different colors.
- It’s arguably the most complex organ after the brain.1
Thus, anyone can appreciate the science behind it and see how advanced eyes are. However, when you ask, “WHY do we have them?”, what answer can really be given? From an evolutionary or atheistic point of view, there frankly CAN’T be a good one.
If you think from an evolutionary point of view, and this isn’t to dismiss all aspects of evolution, the eyeball is not “necessary.” We don’t need it to survive. Yes, there’s no doubt that the eye is extremely valuable! It’s one of the most precious organs we have. It’s the reason we visualize our surroundings and consequently can avoid danger, but it is not a direct reason for survival. When you think about the brain, heart, lungs, stomach, liver, and the mouth, if we don’t have one of them, we are gone! But, we can live without eyes. That is why evolutionarily one has to answer how we got them.
Now if an atheist tries to answer, he or she may say nature caused them to exist or, by chance, some of the early living things on Earth had primitive eyes. Then, through millions and millions of years of natural selection, mother nature, and survival of the fittest, nature enabled the eyes to evolve and possibly those with more advanced eyes survived.But that begs the question – doesn’t it sound like one is saying “mother nature” or “natural selection” has a conscience? How can nature direct anything to that extent? How did it “allow” creatures to have eyes, even though we don’t need them, and then become an organ so prevalent in animals?
