Being Human

Being Human
One of the oldest debates among scientists is what it takes for an individual to be called “human.” The problem is that each discipline has its own criteria for being human.

A physical anthropologist would likely base his definition on the size of the brain, the shape of the mandible, or the position of the foramen magnum–the opening into the brain through which the spinal column passes. A cultural anthropologist might use community structure or communication techniques. In each discipline, the criteria correspond to the tools that discipline uses in its study. All of them are useful, but none present the full picture.

The biblical definition of being human is that being uniquely created in the image of God–that being possessing a soul. Physical appearance and physical characteristics are not part of the biblical definition. The indicator of being created in the image of God is how those spiritual characteristics are expressed. Worship, artistic creation, the use of symbolism, musical creation, and the ability to feel guilt and sympathy are leading indicators.

The media has portrayed the Neandertals as prehumans. Because they were bulky and jut-jawed they seem to fit the picture of prehuman cavemen. Movies have portrayed them as brutes lacking human characteristics. We have maintained for many years that the Neandertals were a race of humans. Recent genetic studies have shown Neandertal genes in the modern human population.

Recently researchers found artwork in three Spanish caves that are attributed to the Neandertals because they predate the time when other races of humans, such as Cromagnons, came to the area. Dr. Francesco d’Errico who has been studying the evidence for Neandertal artwork in the caves says, “Neandertals took modern humans into caves and showed them how to paint.”

The Bible tells us that God created humans in His image. We don’t know when that took place, or how far and how quickly the descendants of Adam and Eve moved out across the Earth. God designed humans to adapt to all kinds of environments, and climatic stresses led to racial variations. The Bible’s statement that “God has made of one blood all nations of men to dwell upon the face of the Earth” is supported by every evidence we have available. However, while being human, our capacity to act like animals and not express our likeness to God’s image cannot be denied.

Alcohol and Dementia

Alcohol and Dementia
“Heavy drinking takes an irreversible, long-term toll on the brain, increasing the risk of all forms of dementia.” That is the conclusion of an exhaustive study of alcohol and dementia. The study involved more than a million adults diagnosed with dementia from 2008 to 2013.

Nearly 60% of early-onset dementia cases were associated with alcohol-related brain damage. Alcohol is toxic to brain cells and reduces blood flow to the brain. People who are intoxicated have literally poisoned themselves. The radical increase in dementia in many forms in our culture is a consequence of the persistent use of alcohol.

When you add the use of nicotine, meth, pot, and other recreational chemical agents to the effect of alcohol and dementia, it is clear that we have an epidemic of brain damage afflictions ahead of us. God has told us that our bodies are special. First Corinthians 3:16 tells us that our bodies are “the temple of God.” First Corinthians 6:15-20 warns against the incorrect use of our bodies. These words are not just about religious separation. God has designed our bodies and our brains for the long haul, and taking care of what God has given us is a sacred responsibility we all have.

Not all dementia is a product of individual abuse. We are realizing more and more that our abuse of the environment also brings us great pain of all kinds. The chemicals we get in our food and the polluted air we breathe are also factors. Christians should be leaders in taking care of what God has created. “The Lord God took the man and put him into the garden to dress it and to keep it” (Genesis 2:15). We are the caretakers of the creation, and we have tended to exploit it rather than to take care of it. The consequences have been disastrous, and that must change.

Bird Migration Data

Bird Migration Data
A fascinating area of study is bird migration. With new technologies, scientists are gathering more bird migration data than ever before.

Arctic terns spend their summers in Alaska and migrate thousands of miles to wintering grounds in South America. Years ago researchers demonstrated that the tern didn’t get the migration information from its parents because terns raised in isolation having no contact with other terns could still make the journey. Terns deprived of visual acuity could still make the journey, so the migration was not by landmarks. The Earth’s magnetic field was not the method because terns equipped with a magnetic scrambler could still make the journey. Similar tests showed it was not by smell or by sound. The researchers concluded that the tern used several navigation tools. If one was lost, the bird would switch to another. We suggested that such a complex system was not a product of chance. It is designed into the tern’s DNA suggesting that God had something to do with the design.

In the March 2018 issue of National Geographic, there is an excellent article titled “Epic Migrations.” Scientists use new tools to collect bird migration data that enables a much more precise understanding of both short and long migrations. Nearly half of all bird species are migratory, so there are a large number of species to study, and scientists are gathering new data continuously.

The long-distance winner of migration is the bar-tailed godwit. One specimen flew 7,150 miles non-stop in eight days from its summering grounds in Alaska to its wintering grounds in New Zealand. In the weeks before migration, godwits build up enormous layers of fat adding more than half their body weight. When they arrive in New Zealand, they have lost all of the fat reserves. Because they do not glide or soar in the journey, their wings are beating all the time. On the way back to Alaska, the birds travel 6,000 miles to China near the Yellow Sea where they spend six weeks. Then they fly 4000 miles back to Alaska. Their departure time for these trips is the same from year to year, influenced only by local weather and winds. They seem to be guided by a precise clock.

Researchers have found an assortment of interesting bird migration data. Studies of frigatebirds in the Pacific show that they sleep while soaring, but only for about 12 seconds at a time for a total of 42 minutes a day. Research shows that half of the bird’s brain is asleep and the other half is awake. Other studies have shown that European starlings use the Sun as a compass and that indigo buntings use stars as a compass. European robins use an internal magnetic compass. When researchers artificially rotated the magnetic compasses by 90 degrees, the birds flew the wrong direction until the Sun came up. Then they reset their magnetic compasses using the Sun for orientation.

Each species of migratory birds seems to have their own built-in devices to make their journeys. The programming of their DNA is incredibly complex and seems to be a designed characteristic built into each species. We can learn a great deal about God by observing the world around us, and truly “we can know there is a God through the things He has made” (Romans 1:20).

One Strange Rock

One Strange Rock
The March 2018 issue of National Geographic features an article with the title One Strange Rock. A NatGeo TV presentation by the same name premiers today. The subtitle of the magazine article says: “13 things that make life on Earth possible.”

For many years we have presented these variables in our videos and audios, books and articles. While new data has expanded these concepts, the fundamental design features of the cosmos remain an excellent argument for the existence of God and His role in the creation. Here are the 13 variables that National Geographic presented to support the idea that Earth is one strange rock:

“#1. OUR PLANET RECYCLES LIFE-FRIENDLY CARBON OVER TIME.
#2. WE HAVE AN OZONE LAYER TO BLOCK HARMFUL RAYS.
#3. WE HAVE A BIG MOON TO STABILIZE OUR AXIAL WOBBLE.
#4. EARTH’S VARIED SURFACES SUPPORT MANY LIFE FORMS.
#5. OUR MAGNETIC FIELD DEFLECTS SOLAR TEMPESTS.
#6 WE’RE AT JUST THE RIGHT DISTANCE FROM THE SUN.
#7. WE’RE SITUATED SAFELY AWAY FROM GAS GIANTS.
#8 THE SUN IS A STABLE, LONG-LASTING STAR.
#9. WE HAVE THE RIGHT STUFF TO HOST A DYNAMIC CORE.
#10. WE HAVE GIANT PLANETS THAT PROTECT US FROM AFAR.
#11. OUR SUN OFFERS PROTECTION FROM GALACTIC DEBRIS.
#12. OUR GALACTIC PATH STEERS US CLEAR OF HAZARDS.
#13. OUR LOCATION IS FAR FROM STELLAR CROWDS.”

We encourage you to view our video series which begins by looking at these variables and showing the probability factors for these and other variables. The point of our discussion is that when you calculate the odds of these things happening by chance, you end up with a probability that is statistically unacceptable.

The conclusion of National Geographic in the article is:

“Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. The product of some 4.6 billion years of cosmic construction, our planet is flush with life thanks to a fortuitous set of conditions, from the optimal chemical makeup of our planetary core to our safe distance from the hidden black hole at the heart of our galaxy.”

Construction suggests an intelligence doing things in a logical order. Blind chance is not a method, and chance produces as much chaos as order. These 13 variables are just astronomical parameters. There are also design features seen in the creation of physical laws and the laws of quantum mechanics that allow stable atoms to exist. Planet Earth is far more than one strange rock.

The more we know of the creation, the more we know of the Creator. Our knowledge is increasing daily which means the evidence for God’s existence also grows daily.

Incredible Human Brain

Incredible Human Brain
As more and more scientific data becomes available, the incredible complexity of the cosmos and our world becomes clearer. A classic example of that is the incredible human brain.

The human brain is not exceptional on a chemical basis. Carbon, hydrogen, oxygen, and nitrogen are the fundamental materials that are present in all brains with traces of various metals also contributing a small part. What is remarkable is the design of the brain and what it can do.

Recent measurements show that the human brain can hold about one petabyte of data. That would be equivalent to a million one gigabyte flash drives. The brain uses more energy than any other organ in the body, but it is only 2% of our total body weight. There are 52 sections to the human brain, each one containing different cells allowing us to do the different things we can do. Every neuron contains about .07 volts of energy. Since a human brain has 86 billion neurons that adds up to about six billion volts–equivalent to 477,777,777 car batteries.

The brain is 75% water, weighs about three pounds with half a pound of that being fat. The incredible human brain is a designed structure that we still have much to learn about it. Our brains speak eloquently of God’s design and the wisdom of God’s creation.

Virtual Faith

Virtual Faith - Cat with Mirror
Atheist virtual faith reminds me of virtual images. I am an old physics teacher. One of the fun discussions that I used to have with my students was when we got into optics and began talking about virtual and real images. Real images are actually formed by light rays. When you take a convex lens or a concave mirror you can project an image of a candle onto a screen. The image is inverted, but it is there. You can block sections of it with your hand, and you can enlarge or reduce the image by changing the distance from the object to the projecting lens or mirror.

The other type of image is a virtual image, which is an illusion. When you look into a plane mirror, you see an image of yourself. The image is not real. It is not actually formed by the light rays, and it cannot be projected. Watching an animal see itself in a plane mirror is always interesting because the animal can be fooled by the realistic virtual image. We all know that magicians can fool us with virtual images as well.

When atheists want to get around questions concerning the existence of God, they frequently bring the word “virtual” into their discussion. Stephen Hawking in his book A Brief History of Time evaded the logical consequences of the second law of thermodynamics by inventing something he called “virtual time.” Lawrence Krauss in his book A Universe from Nothing claims that empty space is actually “a boiling, bubbling brew of virtual particles that are popping in and out of existence on a time scale so short that you cannot see them.” This new definition of “nothing” is based on virtual particles.

Like the virtual image in a plane mirror, all of this is unreal! It is an unscientific proposal because it cannot be falsified or scientifically tested in any way. It is invented purely to justify the rejection of God as the creator. Krauss is fond of saying that there is no need for an intelligent being to will anything into existence because the means for this was already there and available. If you want to invent a religion that believes in unreal particles popping into existence, you are certainly free to do so. That gives the atheist a virtual faith. The problem is that he or she has to believe that from the “boiling bubbling brew” everything necessary for stable matter to exist came about by chance.

We have a booklet “Evidence for Design In the Universe” available on our doesgodexist.org website or from us on request. It contains a list of 47 physical design features that must be present for a planet like ours to exist. We would claim that all of this makes our faith real, and the rejection of God’s existence virtual faith.

Grand Design and Stephen Hawking

The Grand Design
In our March 15 article on this site, we mentioned the death of Stephen Hawking. We noted some of the amazing things that Hawking accomplished. We have received some mail about Hawking and his role as an atheist. How much Hawking’s battle with health issues affected his view of God is hard to answer, but his resistance to believing in God is undeniable as shown in his book The Grand Design.

In his otherwise excellent book A Brief History of Time (Bantam Books, 1988), Hawking did a masterful job of explaining the second law of thermodynamics. He even intimated that the second law was supportive of the existence of God. That was something Hawking didn’t want to do, so at the end of the book he invented something he called “virtual time.” He couldn’t define virtual time, and it is not testable and therefore is not science. By accepting virtual time, Hawking was able to deny that there was a beginning and that the beginning had to be caused by an entity outside of space/time.

Hawking’s first wife was a believer in God and expressed concern about the integrity of the virtual time argument. Many have suggested that Hawking’s belief system was all that the last chapter of the book was trying to defend.

In his 2010 book The Grand Design, Hawking declared that God is not needed to explain the existence of the universe. In an interview, he said, “There is no heaven or afterlife… that is a fairy story for people afraid of the dark.” That was a statement of faith based on the imaginary concept of virtual time. Virtual means unreal. A grand design based on virtual time is not real.

Hawking was an outstanding thinker in cosmology, and he overcame enormous challenges to continue to live a productive life far beyond what was expected. It is sad that he allowed bias to shadow his thinking in areas outside of his specialty. A friend of mine with a Ph.D. in physics says, “My Ph.D. in every-day life really stands for post hole digger.” Like Richard Dawkins and other popular atheists, Hawking was incredibly ignorant in spiritual matters, but a genius in his own field of expertise. Let us admire and praise his professional accomplishments, but not attach much significance to his religious opinions. Tomorrow we will examine “virtual faith.”

Stephen Hawking’s Death

Stephen Hawking's Death
On the morning of March 14, news media carried the news of Stephen Hawking’s death. His family announced, “We are deeply saddened that our beloved father passed away today.”

Hawking was a brilliant physicist and cosmologist and probably the best-known living scientist. He wrote the book A Brief History of Time which was published in 1988. That book holds the Guinness Book of World Records title for being on the Sunday Times (London) bestseller list for an amazing 237 weeks. The book has sold ten-million copies and has been translated into 40 languages. Along with Roger Penrose, Hawking devised the theory that the universe began with a singularity in what has come to be known as the “Big Bang.” In his 2010 book The Grand Design he declared that God is not needed to explain the existence of the universe. In an interview, he said, “There is no heaven or afterlife… that is a fairy story for people afraid of the dark.”

Stephen Hawking lived a remarkable life for a person with a form of ALS, a motor neuron disease. He was diagnosed at age 21, and the doctors gave him two years to live. He survived until age 76 but spent most of those years in a wheelchair unable to move. He could only talk with the aid of a computerized voice.

We are saddened to know that Hawking was never able to accept the Christian faith of his first wife. In the announcement of Stephen Hawking’s death, his three children said, “We will miss him forever.”

We have recently published two postings about Stephen Hawking, and we encourage you to read them by clicking here and here.

Searching for Other Worlds

Searching for Other Worlds
In 1999 astronomers detected the first exoplanet–a planet in another solar system. The number of planets detected orbiting around stars other than our Sun has grown to more than 3,500 today. There are billions of stars in our Milky Way Galaxy so searching for other worlds is just getting started.

NASA’s main tool for finding exoplanets has been the Kepler space telescope. The method of detecting those planets is watching for occlusions. If there is a planet orbiting a star, it will sometimes pass in front of that star from our viewpoint causing an occlusion or mini-eclipse. The planets are too small for us to see, but we can see a small dip in the light coming from the star. If the dip comes on a regular interval that means it might be an orbiting planet. The amount of the dip in light level indicates the size of the planet in relation to its star. Using this method of detection, astronomers have compiled a catalog of detected planets.

As I said, until now the Kepler telescope has been the method for finding most of these planets, but it will soon end its life. However, 2018 will be the beginning of new opportunities to look for exoplanets because of two new satellite-based observatories. Very soon NASA will launch TESS. That stands for Transiting Exoplanet Survey Satellite. By the end of the year, the European Space Agency (ESA) will launch CHEOPS or Characterising Exoplanet Satellite. (Aren’t you glad we have acronyms.)

The Kepler telescope was very good at searching for other worlds, but only in a small area of the sky. TESS will take a much wider view with the hope of finding many more. For obvious reasons, so far most of the planets detected are giant planets. TESS will be targeting bright stars in the hope of finding smaller planets that more closely resemble Earth. Astronomers will be able to target TESS more precisely toward selected stars.

It will be interesting to see what new discoveries will come from the investment of time and more than a quarter of a billion dollars. So far there have been no more than a dozen planets that even come close to being possible outposts for life. As we have said before there are many parameters required to sustain any kind of life and even more to support advanced life. We have also said many times before that whether there is life anywhere else in the cosmos has nothing to say about whether God exists. A God who is great enough to create the cosmos can create life anywhere He chooses. We are just glad He chose planet Earth so scientists can continue searching for other worlds.

Letters in the Sand

Letters in the Sand

What do you see in this picture? Look closely, and you will see evidence of letters in the sand.

Notice the waves that were caused by wind blowing across the desert. Then notice the astonishing thing the wind has done! The wind has created some lines in a fascinating pattern. The lines seem to spell out the name of the world’s largest hot desert—SAHARA. Yes, the Sahara Desert covers most of northern Africa, and to find something this amazing that the natural forces have “written” on the sand is truly unusual.

Wait a minute! Are you suggesting that those letters are not the effect of the wind and natural forces? Are you thinking that maybe an intelligent being actually wrote in the sand? Consider carefully the fact that the Sahara is enormous, and there are vast areas of sand. Given enough time and the proper wind directions, why couldn’t this word show up by natural forces alone? Surely somewhere in that desert, there must be a naturally formed letter—maybe an “S.” Surely in all of that area, it is possible that natural forces could have formed the other letters. Given the billions of grains of sand and enough time, they could just happen to line up in the proper order to spell a word. Couldn’t they?

Okay, you are not buying my story. Perhaps an intelligent being was involved in the formation of this word in the sand. But if you won’t believe me concerning the six letters in the sand, would you believe three-billion letters? That’s how many letters came together in the proper order to form the DNA strands in every cell of your body. That DNA code gives the complete blueprint for YOU. You can read S-A-H-A-R-A in seconds. If you were to read the three-billion letters of the DNA from one of your cells at the rate of one per second, every second of every hour of every day, it would take 31 years. Do you believe that the DNA code came into existence in a completely natural and unguided way?

Oh, you are suggesting that it all started with something simple and then evolved into what it is today. Sorry, but fossil evidence shows that even the simplest bacteria that emerged shortly after the Earth came into existence had extremely complex DNA codes. Life can’t exist without the code. The code is information, and information is the product of intelligence. We suggest that just like those letters in the sand, life can’t happen without an intelligent Creator.
