About eight percent of your DNA did not come from a human being.
Let that sink in for a second. It didn’t come from your parents, your grandparents, or some distant ancestor wandering the plains. It came from a virus. An ancient, prehistoric infection that crawled into your ancestors’ cells millions of years ago and decided to stay.
This isn’t a sci-fi pitch or a late-night creepypasta. This is published, peer-reviewed, settled science. Right now, as you read this, parts of your genetic code are effectively “alien” to the human lineage. And some of that code is actually the reason you’re alive today.
But that’s just the beginning of the rabbit hole.
If we look closer at our genome, we find fingerprints from species that have no names, no bones, and no place in our history books. Scientists call them “Ghost Populations.” On this episode of Broadcasting Seeds, we’re putting science and ancient mythology in the same room to ask the question: Who: or what: is really living inside us?
The 8% Viral Invasion: The Code That Keeps You Alive
We like to think of our DNA as a pristine blueprint of humanity. The reality is much messier. It’s more like a hard drive that’s been hacked, patched, and overwritten for millions of years.
About 8% of the human genome consists of Human Endogenous Retroviruses (HERVs). Usually, a virus hits a cell, hitches a ride, and moves on. But these specific retroviruses infected “germ line” cells: the ones that make babies: and became a permanent part of the human script.
Most people hear “viral DNA” and think of disease. But here’s the kicker: we actually need some of this viral code to survive.
Take the proteins syncytin-1 and syncytin-2. These are critical for the formation of the human placenta. Without these viral proteins, human pregnancy as we know it wouldn’t function. An ancient infection literally gifted us the ability to reproduce.[^1][^2]
The line between “invader” and “infrastructure” blurred a long time ago. We are, quite literally, biological mosaics.

The Ghosts in the Machine: Neanderthals, Denisovans, and the Unknown
If you’ve taken a DNA test lately, you probably know if you have Neanderthal DNA. Most people of non-sub-Saharan descent carry about 1% to 2%.[^3] Then there are the Denisovans: a mysterious group we only know from a finger bone and a few teeth found in a Siberian cave. Their DNA allows Tibetan populations to survive at extreme altitudes.[^4][^5]
We are hybrids. That is a fact. But in 2020, a study out of UCLA by Arun Durvasula and Sriram Sankararaman blew the doors off the “known” human story.[^6]
They analyzed genomes from West African populations and found a massive signal that didn’t match Neanderthals. It didn’t match Denisovans. It didn’t match anything in our database.
They found evidence of a “Ghost Population”: an archaic hominin group that interbred with humans and left behind up to 19% of the genetic ancestry in some groups.[^6] These beings existed. They walked the earth. They had children with our ancestors. And yet, we have zero fossil record of them.
The only proof they ever existed is the “ghost” they left inside you.
The Melba Ketchum Controversy: A Tactical Red Flag
If mainstream science is willing to admit that “Ghost Populations” exist in Africa based on DNA alone, why does it shut down when the same questions are asked in North America?
In 2012, veterinarian and geneticist Dr. Melba Ketchum published a five-year study on over 100 samples of what was alleged to be Sasquatch biological material. Her findings were explosive: the mitochondrial DNA was 100% human, but the nuclear DNA was a “mosaic” of human and unknown sequences.[^7]
The scientific community didn’t just disagree; they nuked the study. They cited contamination and procedural errors. In fairness, those criticisms are part of the record too, and if we’re going to be open-minded investigators, we have to admit both things at once: the study made an extraordinary claim, and extraordinary claims deserve serious scrutiny.[^7]
Now, look at this through a tactical lens. As a veteran, I know that when a narrative is protected with that much aggression, you’re usually hitting a nerve. I’m not saying Ketchum’s study was perfect: procedural grounds are valid: but the refusal of the scientific community to even try to replicate the findings is a massive red flag.
If we accept a “ghost” in a UCLA lab, why is the “ghost” in a North American forest treated like a career-ending joke? Sometimes, institutional boundaries aren’t about evidence; they’re about comfort.

The Universal Story: Nephilim, Gods, and Star People
This is where the science starts to look a lot like the Sunday school lessons or ancient myths you were taught to ignore.
Every major civilization has a “hybrid” origin story. It’s the same narrative across every continent, language, and era: Beings that were not human came down, interacted with us, and produced offspring. That doesn’t automatically prove every tradition is describing the same event... but it does raise the kind of pattern-recognition question honest investigators shouldn’t ignore.[^8][^9][^10][^11][^12]
The Hebrews: Genesis 6 talks about the “Sons of God” (the Watchers) taking human wives and producing the Nephilim: the “mighty men of old.”
The Greeks: Their entire mythology is a genealogy of gods mating with humans to create demigods like Hercules and Perseus.
The Native Americans: Dozens of nations tell stories of the “Star People” who descended and intermarried with the tribes.
The Sumerians: Their kings’ lists include beings who ruled for thousands of years and were “half-divine.”
The Aboriginal Australians: The Dreamtime speaks of creator beings whose essence remains embedded in the bloodlines.
When one culture tells a story, it’s a myth. When every culture tells the same story independently, it’s a pattern. And patterns are data.

The Edge of What We Are Allowed to Consider
In my book, CREATURES AT THE EDGE: Cryptids, Archetypes, and the Human Encounter with Mystery, I talk about how we deal with things that don’t fit the “approved” narrative.
Whether you’re a person of faith who believes in the biblical account of the Nephilim, or a hard-science enthusiast looking at “introgression” and “archaic hominins,” you’re looking at the same reality from different sides of the room.[^6][^8]
Something else contributed to what we are.
We aren’t a clean, single-origin species. We are a composite. We are the survivors of a long, complicated, and possibly supernatural history of mixing. The “Ghost DNA” inside you isn’t just a curiosity: it’s a reminder that we don’t know nearly as much as we think we do.
So, why aren’t these two conversations in the same room? Why is the geneticist not talking to the theologian? Why is the anthropologist not talking to the witness who saw something in the woods?
Because when you put those pieces together, the picture that emerges is uncomfortable. It suggests that “humanity” is a much broader category than we’ve been told.
Join the Conversation
This is the stuff that most people are afraid to talk about out loud. But if you’re here, you’re probably not “most people.”
What do you think? Are these “Ghost Populations” the physical remnants of the Nephilim? Are we living in the middle of a massive institutional cover-up regarding our true origins?
