The brain functions differently than other organs. There is an intelligence to it, the ability to reason, to produce feelings, to dream and plan, to take action, and relate to other people.

Stephen Hawking on God

It has automatic focusing and handles an astounding 1. Yet evolution alone does not fully explain the initial source of the eye or the brain -- the start of living organisms from nonliving matter. Scientists are convinced that our universe began with one enormous explosion of energy and light, which we now call the Big Bang.

This was the singular start to everything that exists: Astrophysicist Robert Jastrow, a self-described agnostic, stated, "The seed of everything that has happened in the Universe was planted in that first instant; every star, every planet and every living creature in the Universe came into being as a result of events that were set in motion in the moment of the cosmic explosion The Universe flashed into being, and we cannot find out what caused that to happen. Steven Weinberg, a Nobel laureate in Physics, said at the moment of this explosion, "the universe was about a hundred thousands million degrees Centigrade The universe has not always existed.

It had a start Scientists have no explanation for the sudden explosion of light and matter. Much of life may seem uncertain, but look at what we can count on day after day: How is it that we can identify laws of nature that never change? Why is the universe so orderly, so reliable? There is no logical necessity for a universe that obeys rules, let alone one that abides by the rules of mathematics. This astonishment springs from the recognition that the universe doesn't have to behave this way.

It is easy to imagine a universe in which conditions change unpredictably from instant to instant, or even a universe in which things pop in and out of existence. Richard Feynman, a Nobel Prize winner for quantum electrodynamics, said, "Why nature is mathematical is a mystery The fact that there are rules at all is a kind of miracle.

All instruction, all teaching, all training comes with intent. Someone who writes an instruction manual does so with purpose. Did you know that in every cell of our bodies there exists a very detailed instruction code, much like a miniature computer program? As you may know, a computer program is made up of ones and zeros, like this: The way they are arranged tell the computer program what to do.

The DNA code in each of our cells is very similar. It's made up of four chemicals that scientists abbreviate as A, T, G, and C. These are arranged in the human cell like this: There are three billion of these letters in every human cell!! Well, just like you can program your phone to beep for specific reasons, DNA instructs the cell. DNA is a three-billion-lettered program telling the cell to act in a certain way. It is a full instruction manual. Why is this so amazing? One has to ask These are not just chemicals. These are chemicals that instruct, that code in a very detailed way exactly how the person's body should develop.

Natural, biological causes are completely lacking as an explanation when programmed information is involved. You cannot find instruction, precise information like this, without someone intentionally constructing it. I was an atheist at one time. And like many atheists, the issue of people believing in God bothered me greatly. What is it about atheists that we would spend so much time, attention, and energy refuting something that we don't believe even exists?! What causes us to do that? When I was an atheist, I attributed my intentions as caring for those poor, delusional people To be honest, I also had another motive.

As I challenged those who believed in God, I was deeply curious to see if they could convince me otherwise. Part of my quest was to become free from the question of God. If I could conclusively prove to believers that they were wrong, then the issue is off the table, and I would be free to go about my life. I didn't realize that the reason the topic of God weighed so heavily on my mind, was because God was pressing the issue. I have come to find out that God wants to be known. He created us with the intention that we would know him. He has surrounded us with evidence of himself and he keeps the question of his existence squarely before us.

It was as if I couldn't escape thinking about the possibility of God. In fact, the day I chose to acknowledge God's existence, my prayer began with, "Ok, you win I am not the only one who has experienced this. Malcolm Muggeridge, socialist and philosophical author, wrote, "I had a notion that somehow, besides questing, I was being pursued.

Lewis said he remembered, " I gave in, and admitted that God was God, and knelt and prayed: Lewis went on to write a book titled, "Surprised by Joy" as a result of knowing God. I too had no expectations other than rightfully admitting God's existence. Yet over the following several months, I became amazed by his love for me. Look throughout the major world religions and you'll find that Buddha, Muhammad, Confucius and Moses all identified themselves as teachers or prophets.

None of them ever claimed to be equal to God. That is what sets Jesus apart from all the others. He said God exists and you're looking at him. Though he talked about his Father in heaven, it was not from the position of separation, but of very close union, unique to all humankind.

Laws of math

Jesus said that anyone who had seen Him had seen the Father, anyone who believed in him, believed in the Father. He said, "I am the light of the world, he who follows me will not walk in darkness, but will have the light of life. Unlike other teachers who focused people on their words, Jesus pointed people to himself.

He did not say, "follow my words and you will find truth. What proof did Jesus give for claiming to be divine? He did what people can't do. He had power over objects He performed miracles over nature People everywhere followed Jesus, because he constantly met their needs, doing the miraculous. He said if you do not want to believe what I'm telling you, you should at least believe in me based on the miracles you're seeing. Jesus Christ showed God to be gentle, loving, aware of our self-centeredness and shortcomings, yet deeply wanting a relationship with us.

Jesus revealed that although he views us as sinners, worthy of his punishment, his love for us ruled and he came up with a different plan. God himself took on the form of man and accepted the punishment for our sin on our behalf. Perhaps, but many loving fathers would gladly trade places with their child in a cancer ward if they could. The Bible says that the reason we would love God is because he first loved us.

Jesus died in our place so we could be forgiven. Such trends have ironically been taking place even as, I would argue, the probability for the existence of a supernatural god have been rising. I should say that I am trained originally as an economist, but have been working at the intersection of economics, environmentalism and theology since the s. In the Princeton physicist — and subsequent Nobel Prize winner — Eugene Wigner raised a fundamental question: Why did the natural world always — so far as we know — obey laws of mathematics? As argued by scholars such as Philip Davis and Reuben Hersh , mathematics exists independent of physical reality.

It is the job of mathematicians to discover the realities of this separate world of mathematical laws and concepts. Physicists then put the mathematics to use according to the rules of prediction and confirmed observation of the scientific method.

Arguments why God (very probably) exists

But modern mathematics generally is formulated before any natural observations are made, and many mathematical laws today have no known existing physical analogues. In some cases the physicist also discovers the mathematics. Isaac Newton was considered among the greatest mathematicians as well as physicists of the 17th century. Other physicists sought his help in finding a mathematics that would predict the workings of the solar system. He found it in the mathematical law of gravity, based in part on his discovery of calculus.

Indeed, Newton made strenuous efforts over his lifetime to find a natural explanation, but in the end he could say only that it is the will of God. Despite the many other enormous advances of modern physics, little has changed in this regard. In other words, as I argue in my book, it takes the existence of some kind of a god to make the mathematical underpinnings of the universe comprehensible. In the great British physicist Roger Penrose put forward a vision of a universe composed of three independently existing worlds — mathematics, the material world and human consciousness. As Penrose acknowledged, it was a complete puzzle to him how the three interacted with one another outside the ability of any scientific or other conventionally rational model.

Proof That God Exists

How can physical atoms and molecules, for example, create something that exists in a separate domain that has no physical existence: This mystery is the same one that existed in the Greek worldview of Plato, who believed that abstract ideas above all mathematical first existed outside any physical reality. The material world that we experience as part of our human existence is an imperfect reflection of these prior formal ideals.

As I would say, mathematics is operating in a god-like fashion. The workings of human consciousness are similarly miraculous. Like the laws of mathematics, consciousness has no physical presence in the world; the images and thoughts in our consciousness have no measurable dimensions. Yet, our nonphysical thoughts somehow mysteriously guide the actions of our physical human bodies. This is no more scientifically explicable than the mysterious ability of nonphysical mathematical constructions to determine the workings of a separate physical world. Until recently, the scientifically unfathomable quality of human consciousness inhibited the very scholarly discussion of the subject.

Since the s, however, it has become a leading area of inquiry among philosophers. Recognizing that he could not reconcile his own scientific materialism with the existence of a nonphysical world of human consciousness, a leading atheist, Daniel Dennett , in took the radical step of denying that consciousness even exists.

As an atheist, Nagel does not offer religious belief as an alternative, but I would argue that the supernatural character of the workings of human consciousness adds grounds for raising the probability of the existence of a supernatural god. Evolution is a contentious subject in American public life. As I say in my book, I should emphasize that I am not questioning the reality of natural biological evolution.

What is interesting to me, however, are the fierce arguments that have taken place between professional evolutionary biologists.

2. The universe had a start - what caused it?

A number of developments in evolutionary theory have challenged traditional Darwinist — and later neo-Darwinist — views that emphasize random genetic mutations and gradual evolutionary selection by the process of survival of the fittest. A number of scientists, such as Francis Collins , director of the U. For my part, the most recent developments in evolutionary biology have increased the probability of a god.
