The material universe operates according to constant fundamental laws of physics and chemistry. They exist as laws because we can expect and predict them to exist as a constant. Without them, science could not be done. Science can only be done because the universe in which we live is intelligible and predictable. These laws describe a reality governed by entropy, where systems trend towards equilibrium and dispersal. Chemical reactions seek balance. Energy gradients dissipate, moving from areas of high concentration to areas of low concentration. Order decays into disorder. This is the passive direction of all matter. This principle becomes more complex as we start to deal with the interaction of different molecules, but the foundational principle remains. Yet, life exists. Life is not passive; it is an active system driven by information and organisation. A living cell functions as an organised and compartmentalised structure of constantly changing but generally maintained disequilibrium (a state of imbalance). It expends energy to build, concentrate, and separate molecules, creating steep chemical and electrical gradients. Cells will utilise these gradients and the principle of diffusion to varying degrees, but all use them. Organic life exists in a state of utilising and overcoming entropy; it constructs and maintains a complex state, both using and overcoming these forces, until it finally succumbs to it. This conflict, the one between the universal tendency towards equilibrium and the specified concentration of biology, presents what I find to be the most compelling argument for the existence for and necessity of God for life to exist. The laws that govern inanimate chemistry cannot adequately explain the origin or persistence of the organisms that exist and survive by opposing them. This in my mind points to the necessity of an intelligence beyond the material world.

The principles at hand are diffusion (the net movement of molecules from a region of higher concentration to one of lower concentration) and osmosis (the diffusion of water across a semipermeable membrane). This process is neither active nor guided; it is the result of generally predictable molecular motion. Where there is no barrier, molecules will move within a space from an area of high concentration to an area of low concentration. Where a barrier is present the same thing will occur to fill that container. The result is an inevitable spreading out until equilibrium is achieved and there is an even distribution of molecules within the space. In its simplest form, this is what can be observed when a tea bag is placed into a cup of boiling water and the tea is evenly distributed through the cup, or when milk is put into the tea. The charge of molecules will result in different molecules with different charges also interacting to reach a state of equilibrium, but again, the principles still remain. Osmosis is a specific case of diffusion, describing the movement of water across a semipermeable membrane (a barrier that allows only certain molecules to pass through) to balance solute (a dissolved substance) concentrations. Both processes are passive and driven by the universal principle of tendency towards higher entropy. This requires no external energy. They are the mechanisms by which nature dismantles order and achieves a uniform state of equilibrium.

Life opposes this principle of dispersion. It is not passive, but an active process of resistance to and utilisation of these forces. Every living cell functions as a container of disequilibrium, a structured environment that operates in opposition to the chemical tendencies of its surroundings. Like an aeroplane, it does not invalidate principles such as gravity, but through active processes utilises energy and these forces to achieve its function. A cell must, for its survival, maintain concentration gradients (differences in the amount of a substance between two areas). It must hoard vital molecules like potassium and glucose at concentrations far exceeding their external levels, while expelling others, like sodium and waste products. This maintenance of these polarities in concentration is the definition of being alive. Once this stops, life ceases to exist. This separation is established and maintained by the cell membrane. This structure is not a simple wall; it is a complex architecture of a phospholipid bilayer (the double-layered structure of a cell membrane) covered with protein channels and pumps. The membrane itself poses a problem for a chemical origin. The challenge is not simply that lipids can form bilayers; the challenge is that this specific barrier must form spontaneously in a chaotic environment that biases towards the dispersion of molecules. How can matter, governed by laws that mandate dispersion into a state of equilibrium, spontaneously organise itself into an ordered, semipermeable barrier designed to actively oppose this very principle by maintaining and repeatedly re-establishing this state of disequilibrium? The formation of such a structure, in isolation, without a pre-existing design or active construction, defies the physical laws of nature that we observe.

We see the principle of diffusion and entropy demonstrated in cell lysis (the rupture of a cell). When a cell dies, its internal form and function fail. The processes that power its active pumps to maintain polarisation cease, and the structural integrity of the membrane is compromised. The membrane ruptures. Instantly, the internal environment, including the high concentration of ions, the folded proteins, and the organised contents of organelles, is exposed. These molecules, no longer held in check, obey these laws which result in diffusion of its materials. They spill out and dissipate into the environment, moving from high to low concentration until equilibrium is reached. Lysis demonstrates this very principle. It is the default state of matter. There is no problem understanding the form and function of organic life and its ability to reproduce when you already have life. But this state of active resistance requires a pre-existing system that is complex and energy dependent. The problem is when it is asserted that mindless matter ordered itself into living cells in opposition to these natural principles without mind or energy.

Consider on the extreme end, the function of a cardiac cell, which relies on repeated and rapid action potentials (rapid changes in electrical charge for signalling and function). In its resting state, the cell maintains a steep electrical and chemical gradient. It uses pumps to push positively charged sodium ions out, creating a high concentration outside the cell. When a voltage threshold is met, sodium channels open. The sodium ions, driven by the passive force of the electrochemical gradient, flood into the cell, reversing its voltage. This is the “downhill” action that the laws of physics predict. But this event is finite. To beat again, the cell must reset. It cannot rely on diffusion, which only moves in one direction. Instead, it must expend energy, in the form of adenosine triphosphate (ATP) (the cell’s main energy molecule), to power the sodium-potassium pumps. These pumps move sodium back out of the cell, against its concentration gradient, re-establishing the “uphill” potential.

The rubber band analogy illustrates this dependence. Diffusion is the snap, a passive release of stored potential. It can only happen once. To get a second snap, a hand must intervene, grasp the rubber band, and expend energy to stretch it, recreating the potential. That hand is the cell’s active transport (using energy to move molecules against a gradient), specifically the ATP-powered pumps. This mechanism uses energy to perform the “uphill” work of moving ions against their gradient. This process is not optional; it is a constant requirement to reset the gradient. Without this active resetting, the function ceases permanently after a single event. Life is not a passive beneficiary of diffusion, it is an active system that uses energy to harness and then oppose diffusion, making continued function possible.

Much discussion about the improbability of life centres on the information code of DNA or RNA. The mathematical improbability or impossibility of a functional gene sequence arising by chance is a significant problem. Yet, this focus on the ‘software’ of life overlooks a greater impossibility: the origin of the ‘hardware’. This is the physical architecture of the cell, the complex machinery required to house and execute the instructions encoded in the DNA. If all we are concerned with is the ordering of amino acids, that is one thing. What happens, however, when those amino acids exist in a pool of molecules all dispersing themselves? This architecture must spontaneously assemble not just without a blueprint, but in active defiance of the physical laws that govern its constituent parts. The same principles of diffusion and entropy that demand dispersal must somehow be overcome to build a complex and functional machine. The code itself is inert; it is information, not action. A strand of DNA, left to itself, does nothing. It cannot build a protein or construct a membrane. For the information to have any meaning, it requires a pre-existing, complex system. This system needs ribosomes (cellular structures that build proteins) to translate the code and enzymes to catalyse reactions. It also needs a cell membrane to maintain the internal environment and metabolic pathways to provide energy. This apparatus must be present and functional with the code. A material explanation requires this interdependent system to emerge from a chaotic environment without an architect, driven only by the forces that dismantle such structures. The information is useless without the complex structure, and the structure cannot be built without the information. This chicken-and-egg problem, rooted in the physical impossibility of spontaneous architecture, presents a more difficult hurdle than the sequencing of the code.

This is the equivalent of placing a tea bag and a sugar cube into cup of hot water. The physical laws of diffusion guarantee a predictable outcome. When these components are added to the water, the tea molecules will move from their high concentration to the low concentration. The sugar will dissolve, and its molecules will spread evenly with some larger gravity dependent parts remaining at the bottom. The end state is a mostly homogenous mixture. This is the unchangeable direction of chemistry from high concentration to low concentration. The origin-of-life equivalent would be to expect the diffused tea molecules to spontaneously weave themselves back into a new tea bag. It would be to expect the dissolved sugar molecules to find each other, re-bond, and crystallise into a cube. Such an outcome is not merely improbable; it is a direct violation of the physical laws governing the system. The heat energy present in the water only serves to accelerate random motion and hasten dispersal. Far from providing a mechanism for construction, that energy provides the mechanism to dictate that spontaneous organisation will not happen, guaranteeing dispersal by powering the random collisions that dismantle order.

The argument is not diminished by acknowledging other physical forces. Forces like gravity aggregate mass, forming planets and stars. The nuclear forces operate at the subatomic level, binding the building blocks of matter. These forces do not provide the directional information required to assemble a functional biological machine at the molecular level. Gravity can pool water and chemicals, but it cannot instruct phospholipids to form a selective barrier. The laws of chemistry and diffusion remain the dominant forces governing how those molecules interact within that pool. These laws dictate dispersion. Therefore, if life originated on this planet, it must have done so within an environment governed by these same physical laws. We must use the physics we know, not appeal to unknown principles. The physics we do know shows a universe where undirected energy inputs, far from being a creative force, are hostile to complex structures. Energy like heat, beyond the narrow tolerances of existing life, increases random motion and denatures proteins, destroying their functional shape. This process is irreversible and is demonstrated by the fact that you cannot uncook an egg. Likewise, radiation breaks atomic bonds in DNA chains. In living organisms, this damage manifests with spontaneous or progressive death such as through as cancers, a clear indicator of destruction, not construction. These forces provide no mechanism for spontaneous organisation; instead, they provide powerful mechanisms for disintegration. The existence of biology is therefore a paradox.

Beyond the problem of architecture, there is the issue of life itself. Even if one could, against all physical odds, reason to the spontaneous formation of a structure resembling a cell, a collection of parts does not constitute a living entity. Having the properties for life and being alive are two different states. This is the difference between a living person and a corpse. A corpse, moments after death, possesses all the physical materials: the genetic information, the proteins, and the cellular structures. Yet, it is not alive. The active process of life has ceased. A material explanation for origins must therefore account not only for the spontaneous creation of the hardware and software but for the ignition of the process itself, a phenomenon that we only ever observe proceeding from pre-existing life.

This conflict points to a truth. The laws of physics and chemistry are necessary for the preservation of life, but they are opposed to its spontaneous formation. A living organism harnesses these principles for its activity and survival. It relies on the predictable nature of diffusion to operate its nervous system and on chemical reactions for metabolism. In this sense, life uses physics. But this relationship is akin to a dam harnessing the principle of gravity. Gravity dictates that water will flow downhill, a principle that, left alone, would create a river. The dam is a complex structure built by design to utilise that natural tendency and channel its energy for a specific purpose. The dam is not a product of gravity; it is a product of design that uses gravity. Likewise, a cell is not a product of diffusion and entropy. It is a system of functional architecture that uses and actively reverses these natural tendencies to achieve an ‘uphill’ state. Everywhere we look, the laws of physics and chemistry dictate that this spontaneous organisation will not happen. The conclusion is that the system of life, an information-rich architecture that resists this physical default, cannot arise from raw material alone and forces that oppose it. It is reasonable to say, therefore, that it is impossible for any life to exist without an external intelligence to design and construct it, but more than this, to give it life.
