How You Can Tell Where It Is

How You Can Tell Where It Is
When you look at something or hear it make a sound, have you thought about how you can tell where it is? How do you determine its direction and how far away it is? Studies of human sight and hearing tell us that two different systems are involved. One system works for sight, and another for sound.

Hold up a finger at arm’s length from your face. Close one eye and look at the finger and what is beyond your finger. Now switch eyes, and you will see that objects beyond your finger appear to move. When you look at a distant object, the brain receives two signals–one from each eye. Based upon how much the background seems to vary, your brain then computes how far away the object is. That’s how you can tell where it is because your brain combines both images to give you a distance perspective.

To locate a sound’s source, the brain gets a signal from each ear. The two signals arrive at slightly different times depending on the width of the skull and the direction of the sound. We cock our heads to take into account the angular location of the source, and the brain creates an auditory spatial map that pinpoints the sound. Your senses handle sound differently from sight because of the difference in speed of the two signals. Light travels at 186,000 miles (300,000 m) per second and sound travels at 1087 feet (331 m) per second. Your brain combines the object’s sound signals received by both ears, and that is how you can tell where it is.

All of this is amazing enough, but researchers at the Max Planck Institute for Biological Cybernetics in Tubingen, Germany, and Queen’s University in Kingston, Ontario wanted to learn more. By using visual tests on a barn owl while monitoring its brain activity, they found that different nerve cells respond to “specific angular differences.” The barn owl used auditory methods with its vision to give it a three-dimensional map of the area. In that way, the owl has an instant picture of where to fly to get the most unobstructed path to its target. The director of the institute said, “We speculate that the brain uses similar algorithms to solve similar problems” such as matching problems.

We take so much for granted about how our basic senses work. As we have said before, David got a small understanding of this which caused him to say in Psalms 139:14, “I will praise you, God, for I am fearfully and wonderfully made. Marvelous are your works.”

Can Design Have Multiple Purposes?

Firefly- Can Design Have Multiple Purposes?
Can design have multiple purposes? That is a question asked by some scientists in a study led by Jesse Barber of Boise (Idaho) State University. The specific design feature they studied is the flashing light of fireflies. Do they have more than one purpose for their flashes?

We always believed that a firefly flashes its light to attract mates. That is reasonable and true, but it is an oversimplification of what the flashing does. Many times living organisms have a warning system built into their design to let predators know they are not good to eat. Barber and his associates suggested that fireflies taste bad and that the flashing warns predators not to eat them.

To test this theory, the researchers put bats that had never been around fireflies into a cage with fireflies. The bats learned in two or three interactions that a flashing bug is not good to eat. Barber says the bats quickly did a routine of “catch, taste, drop.”

Barber’s team then painted the flashing end of some lightning bugs with two coats of black paint so the bats could not see the flashes. Bats faced with the painted fireflies took up to 45 minutes to learn not to try to eat them. It seems evident that the flashing of a lightning bug has more than one function.

Can design have multiple purposes? This study answers that question with a “Yes.” Designing a system that has multiple benefits is engineering at its best. God’s design in nature is amazing! The more we know of the creation, the closer we get to the Creator and the more we see His planning and design.

Natural Disaster and God

Natural Disaster and God Every time natural disaster strikes anywhere in the world, people tend to blame God for what happened. The current examples are the hurricane in the panhandle of Florida, and the catastrophic earthquake in Indonesia. What atheists and skeptics fail to realize about natural disasters is that the vast majority of catastrophes are due to human ignorance and mismanagement. Both of the current crises demonstrate that point.

The major loss of life and devastation in Indonesia is in an area that was built on a restored landfill. Gravel, sand, and dirt were brought in to make living space for what were mostly poor workers and laborers. Engineers have warned for a very long time that the land under the highly populated area was unstable, and the earthquake was enough to cause that land to move in a significant way. You could call this a human-designed natural disaster.

In America, we have the same situation in New Orleans and Los Angeles. New Orleans is built on an area that is soft and prone to flooding, and part of the city is even below sea level. Los Angeles is built in an earthquake active area riddled with faults. It isn’t a question of whether a severe earthquake will happen in the Los Angeles area, it is just a question of when. There will be a catastrophe when that happens, and God will be blamed for causing it.

Hurricane Michael is a demonstration of another human-caused natural disaster. One of the designs of our planet is the method which brings water to areas that would otherwise be a desert. At the equator, the direct sunlight evaporates ocean water which falls as rain causing tropical rain forests. The remaining dry air moves north or south in what is called the “Hadley Cells.” When that dry air cools and returns Earth’s surface at 30 degrees latitude, it produces desert conditions. Most of the world’s great deserts are found at 30 degrees north or south latitude–the Sahara, the Australian Outback, the Mohave, etc.

In the southeastern United States, 30 degrees north latitude runs through northern Florida. That area would be a desert were it not for hurricanes. The heating of the ocean in the summer is sufficient to lift massive amounts of water which are then carried to the land restoring lakes, rivers, and underground aquifers. Without that large water supply system, that area would be a desert like the Sahara. The land area around the Gulf of Mexico in its pristine state had barrier beaches and mangrove forests that moderated the wind and storm surge. When I was a child living in Alabama, we looked forward to “hurricane parties” when we would “button down” and enjoy not having to work. The storm’s damage was limited, and even the storm surge was never a problem. That was 80 years ago.

Since that time, we have modified the shoreline stripping the barrier beaches of vegetation, and building houses where they are easily destroyed by water or wind. Even the vast mangrove swamps that were a buffer to storms have been removed, and channels have been built lined with aluminum houses, golf courses, and boat facilities. It was an invitation for a natural disaster.

We are sympathetic to those who have suffered because of the greed and foolishness of city planners and real estate salespeople. But don’t blame God for the foolishness of human actions.

Does God Exist?

Does God Exist
Perhaps the most important question you will ever ask is, “Does God exist?” The answer you give to that question determines your purpose and outlook on life.

When we look at our universe, our galaxy, and our planet rich with life, we are looking at things that were designed for a purpose. Design gives evidence of a Designer. Purpose gives evidence of a reason for our existence. To believe that everything in the universe came into existence and achieved its present state by chance requires more faith than believing in an intelligent Creator God.

Fifty years ago this month a former atheist, John N. Clayton began the DOES GOD EXIST? project. John is a professional science teacher who came to believe in God as a result of his study in science. The project has continued for half-a-century through lectureships, seminars, publications; and, most recently, websites.

Three years ago, we began a Facebook page which reaches people all over the world with a daily reminder of the amazing design and purpose in the world. In January of 2017, we began daily postings on this website DoesGodExist.tody? About a year ago we started sending weekly emails to those who request to be on our email list. The emails are called “The Best of the Week from DOES GOD EXIST?” They feature links to the previous week’s most popular posts on our Facebook page and this website. This gives people who may not have time to read our posts every day a chance to see what others think are the six best posts from the previous week.

DOES GOD EXIST? is a non-profit program that never asks for money, although we gladly accept donations. This project has continued through the faithful support of many people who believe that God does exist and that Jesus Christ came as God in human flesh to open the way to a relationship with our Creator. If you like our daily Facebook postings, there is just one thing we ask–click the “share” button to share our posts with your friends. If you like our daily posts on this website, tell others about them. We also have other websites and a quarterly printed publication.

We want to continue to remind people daily that there is meaning and purpose in life because we were created by a God who loves us and put us here for a purpose.

Design In Nature

Design In Nature
When a person says that the mindless forces of evolution can easily explain everything that appears to be design in nature, you have to wonder if that person understands the principles of statistics.

From a statistical standpoint the more parameters that exist, the less likely it is that a desired final result will occur. The odds of a single coin flipped into the air and landing on heads is one in two or 1/2. What are the odds of five flipped coins landing heads up? That would be 1/2 multiplied by itself five times. The answer is one in thirty-two or 1/32. If you throw fifty coins up at the same time, the chance of all fifty showing heads is so small as to be considered impossible. (Multiply 1/2 fifty times.)

In nature, we see situations where the odds would be equivalent to throwing a million (or more) coins up and having them all land on heads. There is no way that an open-minded, thinking person can begin to entertain the idea that blind chance can explain such events.

Books and movies on nature often use a phrase like “nature planned…” or “evolution engineered…” or “genetic forces created…” some natural phenomenon. If you truly believe that the forces that created and designed the universe with our planet and everything on it are “mindless, blind, mechanistic chance,” then you can’t attach words that indicate wisdom, purpose, design, engineering, or creativity.

The design in nature is hard to miss. It has to be rooted in the mind of a Designer. Some things are just beyond what mere chance can do.

Honeybee Engineering

Honeybee Engineering
Bees are master engineers of the storing of dense fluids. Their fluid is honey, and they store it in a way that shows excellent honeybee engineering.

Worker bees gorge on honey and excrete slivers of wax. Other workers take that wax and position and mold it into a column of six-sided cells. The bees cluster to keep the temperature of the wax at 35 degrees C (95 degrees F) so that it’s firm but malleable. Each wax partition is less than .1 mm thick with a tolerance of .002 mm. The cell walls must be at a 120-degree angle in relation to each other to make a lattice of regular hexagons.

There are only three regular polygons which pack together snugly without leaving gaps–equilateral triangles, squares, and regular hexagons. The perimeter of a hexagonal cell that encloses an area is less than that of a square or a triangular cell making it the most economical shape. Using the same quantity of wax, hexagonal cells can hold more honey than square or triangular cells. Mathematicians have tried other options, such as using curved sides or a mixture of polygons. They have confirmed that curved polygons could not do as well as straight-line hexagons. Mathematicians can’t beat honeybee engineering.

How do the bees keep the honey in the cells? They tip the cells upward at an angle of 13 degrees from the horizontal. That is precisely the angle needed to stop the honey from dripping out. There is one more problem. How can the bees seal off the bottom of the columns? A flat bottom would not do. Bees construct the base with three, four-sided diamond shapes that meet in a point. Two rows of cells are placed back-to-back and offset so that they interlock. With the cells backing up each other, only one layer of wax acts as the bottom for both cells. Mathematicians have proven that the angles of the diamond-shaped cell bottoms (109.5 and 70.5 degrees) give the maximum volume for storage.

It’s difficult to believe that the honeycomb structure is an accident or the final product of trial and error. Mistakes are usually lethal or at least result in a loss of vital energy resources. Honeybee engineering has fascinated and amazed philosophers and mathematicians since the time of ancient Greece. We think the honeybee engineers learned the principles of structural math from the Master Engineer.

Why Venomous or Poisonous Animals?

Why Poisonous Animals? Eastern Coral Snake
There are 2700 known species of snakes on this planet. Of all those, 412 species, or 15.2%, are venomous. Five hundred thousand people are bitten every year, and 40,000 of them die. People are afflicted by poisonous lizards (two varieties), frogs, salamanders, and a variety of toxic insects. This brings up the question of why venomous or poisonous animals exist if a loving God made all things.

If you or someone you know has suffered an attack by one of these animals, you know that even when it is not deadly, it’s still a very unpleasant experience. The skeptic and even the non-skeptic is moved to ask why God would create a reptile or amphibian that could cause such terrible discomfort to humans. Why should an innocent child die because of picking up a pretty ribbon that turned out to be a coral snake?

If you have experienced an encounter, no canned explanation will make the pain and loss go away. But can we make any sense of why venomous or poisonous animals exist?

We must first begin by recognizing that God may not have created these animals as they are today. God did not create many animals (dog and cattle breeds for example) as they are today. They have changed over the years. It is possible that the same is true of poisonous animals, and their original ancestors may not have been deadly. However, the complexity of the poison systems in reptiles and amphibians seems to make this explanation a little imaginative, if not impossible. Even if true, it does not remove God’s awareness of the situation.

A better answer to this question of why venomous or poisonous animals exist lies in the wisdom and planning of God. The Bible says we can know God exists and see His wisdom by looking at the creation. (See Romans 1: 19-23; Psalms 19: 1.) The more we learn about the creation, the more we see God’s design.

One thing we have come to understand is the need for balance in ecosystems. We know that all living things serve a purpose in their natural setting. Animals and insects eat plants which keep the plants from crowding themselves out. Carnivorous animals keep the plant-eaters from wiping out their food supply. Because animals do not fear death as we do, the system is not as cruel and as callous as some would have us believe. In a balanced system, things generally function smoothly and efficiently.

One of the critical factors in maintaining balance is the survival of reasonable numbers of all species. Most reptiles and amphibians are soft-bodied, slow, and generally vulnerable. Camouflage protects some, but the venom or poison glands of others are necessary to do the job. Not only does this protect that animal, but any animals that look similar. Venom also helps the animals catch their food. Rats and mice are the primary food source of many snakes, but without the venom, the snakes could never catch them. Very few venomous snakes or poisonous animals of any kind will attack a human. Most bites occur when a person molests an animal. The obvious purpose of the poison is defense and obtaining food. Accidents do happen, but the poison was not given as a device to be used on humans.

Another important factor is that venomous and poisonous animals provide medicines that we cannot secure from any other source. Medicine from snake venom stops the agents which cause rheumatoid arthritis. There are many other examples of ways science has found to use the poisons from animals.

We can see that there are reasons why venomous and poisonous animals exist. Venomous animals do not prove that God didn’t thoughtfully and intelligently design the creation. We sometimes have to look a little more closely to see the ultimate wisdom of the Creator.

Grand Canyon Formation

Grand Canyon Formation
As we told you before, this is the week of the 2018 Canyonlands Tour. We mentioned the plaque at the Grand Canyon watchtower with the verse from Psalms. Today, we would like to share with you a video segment from a previous field trip to the Grand Canyon. In the video, geologist and teacher John Clayton uses the diagram shown above as he describes the layers of the Canyon and the various processes that formed them. The Grand Canyon formation processes are complex and involve God’s work through natural forces over a vast span of time.

Evolution Does Not Explain Creation

Evidence from Cosmology
The notion of God as the creator has escaped our world today. We have not understood that there was a beginning, that God caused the beginning, and that His imprint is on all we see around us. We have been told that evolution explains all these things, but in reality, evolution doesn’t address the question. Evolution does not explain creation.

Evolution assumes that time has been created. Evolution assumes that space has been created and that matter/energy has been created within space/time. Evolution assumes that forces we are just beginning to understand shaped the matter/energy in space/ time so that stable physical matter came into existence. It assumes that the properties of matter/energy caused it to become organized into galaxies, and stars, and solar systems.

Evolution further assumes that within one of those solar systems a planet was created within the Goldilocks zone where water could exist as a liquid. On that planet, carbon and oxygen and heavy metals were produced to allow tangible matter to exist for long periods of time. Then evolution assumes that within a limited time these materials came into existence in an environment and with a catalyst that could produce life.

Once all those assumptions have been made, evolution attempts to explain how that first life changed to eventually become us. In other words, evolution tries to explain how once the creation happened, things got to be as they are today. Evolution does not explain creation.

Why Roosters Don’t Go Deaf

Why Roosters Don't Go Deaf
Roosters are loud! They can hit volumes as high as 140 decibels which is the level of sound on an aircraft carrier deck. For humans, a noise above 120 decibels, about the level of a chainsaw, can cause permanent hearing damage. So you may wonder why roosters don’t go deaf.

Belgian researchers writing in the journal Zoology have the answer. They examined the skull structure of the birds. The researchers found that they have a built-in defense against loud sounds in the form of a sound barrier. When a rooster adjusts its head and neck to crow, small flaps of tissue close the ear canal. They effectively act as earplugs to dampens the noise significantly.

On top of that, the study reveals that roosters can regenerate the tiny hair cells deep within the ear that can become damaged by loud noises. Humans can’t do that, which is why deafness caused by loud sounds is permanent for us. For roosters, a degree of deafness would likely only be temporary if it happened at all.

“Micro-CT scans of a rooster and chicken head show that in roosters the auditory canal closes when the beak is opened,” the researchers wrote. “In hens the diameter of the auditory canal only narrows but does not close completely. A morphological difference between the sexes in shape of a bursa-like slit which occurs in the outer ear canal causes the outer ear canal to close in roosters but not in hens.”

So now you know why roosters don’t go deaf. God’s design in every living thing on Earth shows wisdom and an exceptional understanding of the problems that each species faces. The more we learn about the creation, the more we understand the wisdom and creative nature of God. “We can know there is a God through the things He has made” (Romans 1:19-20).
