From Dust to Life: Genesis, Nature, and the Human Microbiome
What emerging science can teach us about our relationship with creation—without asking Scripture to function as a biology textbook.
“And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life…” — Genesis 2:7 KJV
Genesis presents a beautiful picture of human life: we are formed from the earth, sustained by God’s breath, and placed within creation—not outside it.
Modern microbiome research gives us another reason to appreciate this connection. Our bodies are not isolated structures. We live in relationship with an enormous community of microscopic organisms, while our food, surroundings, habits, and environment continually influence that community.
WHAT IS THE MICROBIOME?
The human microbiome is the collection of microorganisms—and their genetic material—living in and on the body. These communities include bacteria, fungi, viruses, and other microbes found primarily in the digestive tract, mouth, skin, respiratory tract, and reproductive and urinary tracts.
The gut microbiome participates in functions such as breaking down components of food, producing certain metabolites and vitamins, interacting with the immune system, and helping maintain the intestinal environment.
Not every organism is beneficial, and more diversity is not automatically better in every circumstance. A healthy microbiome is better understood as a balanced, functional ecosystem—not a simple count of “good” versus “bad” bacteria.
WHAT THE NEWEST AGING RESEARCH ACTUALLY FOUND
A July 2026 University of Hawaiʻi study examined stool and blood samples from 123 adults. Researchers found that certain patterns in the gut microbiome were associated with a molecular measurement called DunedinPACE, which estimates the pace of biological aging.
Microbial differences accounted for approximately 15% of the variation in this aging measurement. Bifidobacterium adolescentis was among the organisms associated with slower biological aging, while another species was associated with faster aging.
This was an important proof-of-concept study—but it did not demonstrate that particular bacteria directly control how quickly a person ages. It also did not prove that taking a probiotic containing one organism would slow aging.
The most accurate conclusion is that the microbiome may carry meaningful information about biological aging and deserves further investigation. The researchers emphasized that additional studies are needed before microbiome changes can be treated as a longevity intervention.

FROM THE SOIL TO THE TABLE
Genesis 2:7 does not describe the microbiome scientifically, yet it offers a meaningful theological foundation: human beings are embodied creatures made from the earth and dependent upon God’s creation.
“Behold, I have given you every herb bearing seed… and every tree…” — Genesis 1:29 KJV
Plants grow through relationships among soil, roots, water, sunlight, nutrients, and microorganisms. When we eat plants, we receive fiber and other compounds that may nourish members of the gut microbiome.
Researchers are also studying how environmental biodiversity, outdoor spaces, animals, food, soil, buildings, and daily exposures may interact with human microbial communities. The connection is complex. Scientists have not established that simply touching soil will improve the gut microbiome, and environmental microbes may be helpful, neutral, or harmful.
Still, the broader picture is compelling: soil, plants, microbes, food, animals, and people belong to interconnected ecosystems. A National Academies review concluded that environmental microbial exposure may be important to immune, metabolic, and nervous-system development, while acknowledging that the specific connection between the soil microbiome and human health remains incompletely understood.

CARETAKERS—NOT CONQUERORS—OF CREATION
Genesis 2:15 says that God placed humanity in the garden “to dress it and to keep it.” The passage suggests stewardship, participation, and responsibility.
Caring for ourselves and caring for creation do not have to be separate practices. Thoughtful habits may include:
• Eating a varied selection of plant foods when medically appropriate
• Spending time outdoors and appreciating natural spaces
• Gardening with reasonable hygiene and safety precautions
• Protecting clean water, healthy soil, and local biodiversity
• Using antibiotics only as prescribed and discussing concerns with a licensed clinician
• Remembering that supplements and probiotics are not universal solutions
These practices should not be treated as cures or guarantees. They are ways of participating more intentionally in the environment God has entrusted to us.
FAITH AND SCIENCE ASK DIFFERENT QUESTIONS
Science investigates measurable mechanisms: Which microbes are present? What are they producing? How are they associated with diet, immunity, metabolism, disease, or aging?
Faith asks questions of meaning: Who created life? What responsibilities accompany it? How should we care for our bodies, our neighbors, and the earth?
We do not need to force Scripture into the role of a microbiology textbook. Nor must scientific discovery remove wonder from creation. For me, each new discovery is another opportunity to appreciate the wisdom, complexity, and interdependence built into life.
Genesis tells us that we came from the dust and received life from God. Microbiome science reminds us that we remain deeply connected to the living world around us.
Perhaps wellness begins partly with remembering that we were never created to live apart from that world.
