Does God exist? Is there any scientific evidence to prove that God exists?

Since I haven’t talked about science in a while, I thought that now would be a good time to list some of the more common arguments for a Creator and Designer of the universe and/or intelligent life. I like to use arguments drawn from mainstream science that do not assume the Bible or inerrancy or anything specifically religious. The arguments below all show that the reality we live in exhibits effects in nature that are not explained by particles in motion, chance and the operation of natural laws.

First, here’s the list of a few of the better-known arguments:

The average knuckle-dragging atheist will not be familiar with any of these arguments, will have never seen them used in academic debates, and will not even click through to read about them. That’s atheism these days – it’s non-cognitive. Atheism is all about escaping from moral values and moral obligations, which are not even rationally grounded by atheism.

The point of being familiar with these arguments is to show that religion and science are virtually identical. Both are trying to explain the external world. Both are bound by the laws of logic. Both use evidence to verify and falsify claims. For example, the discovery of the origin of the universe falsifies Hinduism, Buddhism and Mormonism, but it leaves Christianity, Islam and Judaism unscathed. All religions make truth claims and those claims can be tested against what science tells us about the world.

What is the significance of scientific progress for Christians?

Some general points to know when presenting these arguments.

1. You need to emphasize that atheism is in full flight away from the progress of science. Each of these arguments has gotten stronger as the evidence grew and grew. For example, scientists had to be forced to turn away from the eternal universe as new discoveries arrived, such as the cosmic microwave background radiation measurements. Scientists had to turn away from the view that the cosmological constants are nothing special, as more and more fine-tuned quantities were discovered.

2. Christians need to pay attention in school and score top grades in mathematics and experimental sciences. Science is God-friendly, and we need to have Christians doing cutting edge research in the best labs at the universities. Think of the work done by Doug Axe at Cambridge University in which he was able to publish research showing that very few sequences of amino acids have biological function, so getting functional sequences at random is virtually impossible. One of Doug’s papers is here. We need more people like him.

3. Each of these arguments needs to be studied in the context of polemics and debates. The best way to present each of these arguments is by presenting them as a struggle against opposing forces. For example, when talking about the big bang, emphasize how atheists kept trying to come up with eternal universe speculations. When talking about the fine-tuning, talk about the unobservable multiverse. When talking about irreducible complexity, talk about the co-option fallacy. Don’t preach – teach the controversy.

4. Don’t make lazy excuses about how scientific evidence doesn’t persuade non-Christians. Science is absolutely the core of any argument for Christianity, along with the case for the resurrection of Jesus. Christianity is about knowledge. Christians who refuse to subject their faith to science are probably just trying to make sure that Christianity isn’t so true that it dictates how they should live. They like the uncertainty of blind faith, because it preserves their autonomy to disregard Christian moral teachings when it suits them.

5. The purpose of linking your Christian faith to scientific arguments is to demonstrate to non-Christians that Christianity is real. It is not a personal preference. It is not something you grew up with. It is not something you inherited from your parents. When you link your Christian faith with scientific facts in the external world, you are declaring to non-Christians that Christianity is testable and binding on everyone who shares the objective reality we live in. You can’t expect people to act Christianly without showing that Christianity is objectively true.

6. Scientific arguments are tremendously useful even for believing Christians, because sometimes it is difficult to act in a Christian way when your emotions are telling you not to. When your feelings make it hard for you to behave Christianly, that is when scientific evidence can come into play in order to rationally justify acts of self-denial and self-sacrifice. For example, scientific evidence for the existence of God is a helpful counterbalance to the problem of apparently gratuitous evil, which often discourages Christians.

My complete index of arguments for and against Christian theism is here.

UPDATE: I notice that in the popular culture, people are not really aware of these arguments, and are still arguing for religious faith based on pragmatism and personal experience, not on evidence. Using reason and evidence is much better, and it’s what the Bible teaches, too.

Is there scientific evidence for an intelligent designer?

Dr. Walter L. Bradley
Dr. Walter L. Bradley

Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor, and a great example of the integration of Christian faith and a stellar academic career. He is not a “secret-service” Christian. Rejecting the notion of safe, private Christianity, he instead projects his Christian faith outward, where his students and colleagues can be aware of his beliefs.

Below I analyze a lecture I chose from the hundreds of public lectures he has given all over the world on the integration of Christian faith with other public, testable areas of knowledge. In this lecture, entitled “Is There Scientific Evidence for an Intelligent Designer?“, Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best current atheist response to this is to speculate that there may be an infinite number of unobservable and untestable universes. (I.e. – the Flying Spaghetti Monster did it)

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best atheistic response to this is to speculate that there is an unobservable and untestable hyper-universe outside our own. (I.e. – the Flying Spaghetti Monster did it)

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current atheistic response to this is to speculate that unobservable and untestable aliens seeded the earth with life. (I.e. – the Flying Spaghetti Monster did it)

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Conclusion

In all three areas, scientists expected that the data would be consistent with atheism. First, scientists expected that life could exist even if the physical constants and ratios were altered. The progress of science said NO. Second, scientists expected that the universe would be eternal. The progress of science said NO. Third, scientists expected that the origin of life would be simple. The progress of science said NO.
