Oldest concrete in the world, 12900 years old, was found on the Isle of Pines in the Pacific Ocean. Nobody knows who created it.
The Isle of Pines is an island in the Pacific Ocean, in the archipelago of New Caledonia, an overseas collectivity of France. Scattered across the central plateau of the island lie more than 300 poorly understood mounds, some of which have been excavated and found to have concrete cores. No human remains or man-made objects have been found in the mounds; one snail shell embedded in excavated concrete was carbon-dated to 12,900 ± 450 years old. Much as with the American mima mounds, there is no consensus on what these mounds are.

Truth of our reality.
Grab some popcorn and possibly a tinfoil hat.
Note: TLDR is somewhere in the comments section.
As everyone has noticed more and more. It is not just technology and history which is obscured. There is also a hidden underlying fundamental truth to perception itself. Like the the young kids say. "math is not math-Ing"
A little preface, I grew up using rotary phones & land lines. Raised with a very religious background full of doubt and skepticism. As they say “until you see it for yourself” or have experienced it, how can you believe it? Yet, over the course of my life I have come across many unexplainable real experiences.
This hasn't been the first time we've gotten this close to a partial disclosure either.
Let me introduce you to just a sliver of our current reality through a curated small list of videos from individuals who are starting to ask these questions.
Note: The “big” picture is much larger than most think. (It encompasses everything you can think of)
Lets start off this journey with the last closest time of disclosure of alien/ufo/technologies:
- YouTube Channel - Polarity - Does an amazing deep dive on this exact topic on this stream. Lecture of famous life long abductee Dr. Karla Turner
In contrast, this angle by a modern investigative journalist who only started searching after a real life experience .
- YouTube Channel - Cabin in the woods - The story of "big foot". Cryptid technologies
Transitioning our focal point to a more spiritual lens.
- YouTube Channel - MBB Dr. Mayim Bialik- Listen to a current message (April 2026) from another being. A channeled message from Z. (There is a part 2)
Lastly, let's tie in the overall control system and how it might operate behind the veil controlling your perception.
- You tube channel - Polarity - The Khazarian Mafia & Cult of Ba’al: How Humanity Fell Into Deception
I am not here to convince anybody of anything. It is up to you as the on lookers to start asking the right questions for yourselves. Formulating your own perspective and seeking the truth.
Note: For people (and human systems), controlling perception is powerful because:
- Perception shapes belief → what you think is true
- Belief shapes behavior → what you choose to do
- Behavior shapes outcomes → what actually happens in the world
So if you can influence how others see reality, you don’t need to force them—you can guide their decisions indirectly. Regardless, lying about fundamental reality is nefarious none the less.
If you made it this far you're a "real" one. Thanks for reading.

youtube.comThe plant that makes Stones soft like clay
THE SECRET OF SOFTEN STONES: THE LOST TECHNIQUE OF THE INCAS
I read in a collection of diaries by Spanish explorers in South America about one who described walking through a field of large red leaves. The spurs on his boots had completely melted as a result. His indigenous guide explained to him that these plants were a type of stone-softening herb, which they had used in the past to rub hard stones to soften and shape them, and to construct those inexplicable structures where, in some cases, huge stones were fitted together with millimeter precision, like a puzzle.
Does anyone know more about this?
I wonder why it seems noone is actively following & researching this lead?
Here is a bit more i found:
FYI, (https://davidpratt.info/andes2.htm)
"In an interview in 1983, Jorge A. Lira, a Catholic priest who was anexpert in Andean folklore, said that he had rediscovered the ancient method of softening stone. According to a pre-Columbian legend the gods had given the Indians two gifts to enable them to build colossal architectural works such as Sacsayhuaman and Machu Picchu. The gifts were two plants with amazing properties. One of them was the coca plant, whose leaves enabled the workers to sustain the tremendous effort required. The other was a plant which, when mixed with other ingredients, turned hard stone into a malleable paste. Padre Lira said he had spent 14 years studying the legend and finally succeeded in identifying the plant in question, which he called
‘jotcha’. He carried out several experiments and, although he managed to soften solid rock, he could not reharden it, and therefore considered his experiments a failure.4 Aukanaw, an Argentine anthropologist of Mapuche origin, who died in 1994, related a tradition about a species of woodpecker known locally by such names as pitiwe, pite, and pitio; its scientific name is probably Colaptes pitius (Chilean flicker), which is found in Chile and Argentina, or Colaptes rupicola (Andean flicker), which is found in southern Ecuador, Peru, western Bolivia, and northern Argentina and Chile. If someone blocks the entrance to its nest with a piece of rock or iron it will fetch a rare plant, known as pito or pitu, and rub it against the obstacle, causing it to become weaker or dissolve. In Peru, above 4500
m, there is said to be a plant called kechuca which turns stone to jelly, and which the jakkacllopito bird uses to make its nest. A plant with similar properties that grows at even higher altitudes is known, among other things, as punco-punco; this may be Ephedra andina, which the Mapuche consider a medicinal plant."
"The construction of monuments like Sacsayhuaman and Machu Picchu is a testament to the skill and ingenuity of the Incas. However, the technique used to carve and shape the stones remains a mystery. According to legend, the gods would have gifted the Incas two magical plants: coke, which allowed them to withstand pain and physical exhaustion, and another plant that allowed them to soften stones.
Father Jorge Lira, an expert in Andean folklore, claimed to have discovered the secret of the second floor. According to him, it was the "jotcha", a plant that, mixed with other components, turned the hardest rocks into a moldable and moldable substance.
Although Father Lira passed away without revealing the secret of the jotcha, other researchers have suggested that the plant in question could be the Andean Ephedra, also known as "bone-breaker". This plant, which grows in the Andean mountains, has medicinal properties and has also been used to dissolve iron and stone.
However, the identification of the jotcha with the Andean Ephedra is not universally accepted, and the secret of the Inca technique to soften the stones remains a mystery."
Unexplained noises heard five years ago; have never been able to forget it
Hi!
I just made this reddit account because I have always wanted to share this story and it has kind of really badly affected me ever since. Im trying to give all of the context because I am really looking for any proposed explanations- please let me know if you have thoughts! One night, I was home with my ex-boyfriend at the time; we were seniors in high school, and my parents were gone for the weekend, so I naturally invited him over. I'm a very anxious person, so I was so so nervous to do this as I am very close with my parents but I think subconsciously I didn't want to be home alone because I've always felt a bit scared while alone so i invited him over. Also, at this time my family had two cats in the house, and for more context the only toys that we have in the house are in our basement which is quite soundproof- you can't hear noise from it in the room that I was in (the living room/TV room). My ex boyfriend and I were just laying on the chaise couch thing watching TV- my house is quite open layout, so the chaise couch faced one doorway into the front room and on the left of the chaise couch is very open to the full kitchen.
So, we were watching TV at a normal-volume level, and then I heard a noise. The best way I can describe it is a mischevious child's laugh, but just a bit deeper than like a young child's tone. I immediately turned to my boyfriend and paused the tv, and asked him if he just "heard that", to which he said yes- he was also visibly scared. We sat there in the silence for a few seconds (not sure how long, this was a while ago), and then not too long after we heard a noise again: clear as day, loud, sounding like it was coming from directly in front of us, a child's laugh- even clearer than the one before because we had paused the tv. My boyfriend and I didn't even exchange words, we both ran into the kitchen and grabbed knives, huddled in the corner of the kitchen, and when I could bring myself to make a noise, I called my parents and broke into hysterics. They called the neighbors who came over and literally searched the whole house because I was so scared, and found nothing. They left, and the rest of the night was normal.
My immediate reaction and everyone else's was that it must have been the cats. I cannot describe to you how un-catlike this noise was, and at that time we had had these cats for nearly 15 years and I had NEVER heard them make a noise even slightly similar to that.
So yea, if anyone has any thoughts please let me know!! I'm staunchly not a believer in supernatural stuff and i don't have any religious affiliation, so having this thing that I have never been able to explain to myself for so long has really affected me negatively.
What could this be?
Yesterday it was my birthday. I had a few family members over my apartment and while we were sitting on the couch, we quickly saw an empty plastic snapple apple juice bottle move by its self. I had it located on top of a table couple feet away. I saw it from the corner of my eye, my sis im law and mom also saw. Can anyone explain this to me? A ghost? Very strange!
I clean an airbnb with my mom in Arizona. I was doing a deep cleaning when i found these behind the fridge, under every cabinet shelf and drawer in the kitchen. Im not sure if it was the previous owners of the home or a guest at some point. Is it some kind of affirmation or manifestation?

The Kandahar Giant – The Nephilim of Afghanistan - U.S. Soldiers Break Their Silence
In 2002, deep in the mountains of Afghanistan, a U.S. Special Forces unit encountered something out of myth.
A 12-foot, red-haired giant with six fingers on each hand, double rows of teeth, and a stench like decay itself. The creature was said to have emerged from a cave, impaled a soldier with a massive spear, and was ultimately brought down in a hail of gunfire.
Flown out under extreme secrecy, the body was reportedly airlifted by Chinook and transferred onto a C-17 Globemaster, never to be seen again.
Some say it was a remnant of the Nephilim, the ancient hybrid race mentioned in biblical texts. Others believe it was one of the cave-dwelling giants long feared by Afghan tribes, described in local legends for centuries.
These oral traditions speak of towering red-haired beings, with piercing eyes that glow in the dark, claw-like nails, and voices that echo across the mountains.
Villagers still whisper about disappearances, roars with no source, and ancient cave networks said to be home to these giants, guardians of forbidden secrets and inner earth entrances.
Two decades later, witnesses have begun to speak.
A pilot claims to have flown the body. A soldier says he was there when it was killed.
This is the story of The Kandahar Giant, the legend the government buried but the mountains never forgot.
Weird knock.
I was around 9 at the time of this happening. I was in Clarkston Michigan at the time. I lived in a small shady and scrappy neighborhood. There were car thieves in the area. but that isn't important. One day at 12 am. Somebody knocked on our door. This was scary because it was very late. And nobody we knew was in the area. I looked out my window, but no one was there. The thing is, they used our secret knock. meaning they must have lived nearby. and or listened to us do the knock. I don't know if it was just some prank from kids or not. But it was scary.
The Hum: a low-frequency sound heard in dozens of cities worldwide that only 2% of people can perceive. Some cases have been traced to industrial sources. Others — including the original Taos Hum that prompted a federal investigation — remain unexplained after 30+ years.
In the early 1990s, residents of Taos, New Mexico, started complaining about a low-frequency humming sound that wouldn't stop. It was there when they went to bed and there when they woke up — a steady, throbbing drone, like a diesel engine idling somewhere over the horizon. It was louder at night, louder indoors, and impossible to locate. Not everyone could hear it. Roughly 2 percent of the Taos population reported the sound. The other 98 percent heard nothing.
The complaints were persistent enough that Congress funded an investigation. A team from Los Alamos National Laboratory, Sandia National Laboratories, and the University of New Mexico deployed specialized acoustic equipment tuned to frequencies between 8 and 80 hertz — the range where sound registers more as vibration than tone. They found that the hearers were telling the truth: something was being perceived, each person at a slightly different frequency between 32 and 80 hertz. They could not identify a source. The investigation ended inconclusively. The sound did not.
The Taos Hum was not the first and was nowhere close to the last. The case files share a strange common profile across decades and continents: a low-frequency drone, typically between 30 and 80 hertz, heard indoors more than outdoors, worse at night, worse in quiet environments, perceived by a small minority of the population while the majority hears nothing at all.
The documented cases
Bristol, England, reported a persistent thrumming in the 1970s — about 800 people heard it. It was tentatively blamed on vehicular traffic and factories running 24-hour shifts but never definitively explained, and the reports eventually faded. A 1973 university study of 50 Bristol Hum complainants found the sound always peaked between 30 and 40 hertz, was heard only during cool weather with a light breeze, and was more common in early morning. Researcher Philip Dickinson suggested at an Institute of Biology conference that year that the sound could result from the jet stream shearing against slower-moving air, possibly amplified by power line structures or by rooms with corresponding resonant frequencies. Another acoustics researcher dismissed his hypothesis as "absolute nonsense." The case was never closed.
Windsor, Ontario, erupted in late 2011 with a low droning vibration loud enough to provoke 22,000 reports to officials in a single evening in 2012. Kokomo, Indiana. Largs, Scotland. Auckland, New Zealand. Bondi, Australia. Frankfurt and Darmstadt, Germany. San Francisco's Sunset District, where residents reported it as recently as 2024. Kerry County, Ireland. The Hum has been documented on every inhabited continent.
The cases that got solved
The Windsor Hum was traced, with reasonable confidence, to Zug Island — a heavily industrialized section of River Rouge, Michigan, across the Detroit River from Windsor. Canadian officials identified the area as the likely source, but jurisdictional politics complicated the investigation: local authorities couldn't access the island, and U.S. Steel, which operated a steel mill there, said no new equipment had been installed around the time the noise became noticeable. The resolution came accidentally. When the blast furnaces were deactivated in April 2020 during the pandemic shutdowns, the Hum stopped. When operations resumed, the Hum returned.
In Darmstadt, Germany, investigators in 2022 identified multiple sources: two faulty air conditioner units, a faulty heat pump, and three structural noise protection measures on energy generation plants that were themselves producing low-frequency noise. In Kokomo, industrial fans were implicated, though some reports persisted after the fans were addressed.
These solved cases share a common mechanism. Industrial equipment generates low-frequency noise that propagates through the ground or air and is amplified by the resonant properties of certain buildings. A room with the right dimensions can amplify a faint 40-hertz signal into something perceptible — the way a wine glass vibrates when you hit the right frequency. Low-frequency sound penetrates walls more effectively than higher frequencies, which explains why the Hum is louder indoors. It's louder at night because ambient noise drops, unmasking sounds that were always present but drowned out during the day. It's louder in suburban and rural environments than in cities for the same reason: less background noise.
The cases that didn't get solved
The Taos Hum investigation found no industrial source. The full federal investigation team — Los Alamos, Sandia, University of New Mexico, with custom-built acoustic instrumentation — could not identify any external generator that explained the reports. The Bristol Hum was never definitively explained. Auckland researchers found some low-frequency sources, silenced them, and the complaints continued. The Hum in Kerry County, Ireland, was investigated and remains unexplained.
The pattern — some cases explained by identifiable mechanical sources, others remaining stubbornly unresolved — suggests that "the Hum" is not a single phenomenon. It's a symptom that can have multiple causes, some of which are industrial, some of which may be biological, and some of which haven't been identified.
The biology of hearing things that aren't there (or are)
The human ear is not a passive microphone. It generates its own sounds — called spontaneous otoacoustic emissions — produced by the motion of the outer hair cells in the cochlea. Studies show that 38 to 60 percent of adults with normal hearing produce these emissions, though most people are unaware of them. In quiet environments, some individuals perceive their own otoacoustic emissions as a faint hissing, buzzing, or humming. The Taos investigation considered this as a possible explanation: the Hum might not be coming from outside the ear but from inside it.
This hypothesis explains some features of the phenomenon — why only a small percentage of people hear it, why it's worse in quiet environments, why earplugs sometimes make it louder rather than softer (blocking external noise unmasks the internal signal) — but it doesn't explain the geographic clustering. If the Hum were purely a biological artifact, it should be distributed randomly across the population, not concentrated in specific towns during specific time periods. The geographic pattern suggests an external stimulus, even if the perception of that stimulus is mediated by individual differences in auditory sensitivity.
Low-frequency tinnitus is another biological candidate. Tinnitus typically manifests as high-pitched ringing, but a subset of cases involve low-frequency perception in the range of the Hum. Some researchers have proposed that the Hum represents a form of tinnitus that is triggered or modulated by environmental low-frequency noise too faint for most people to perceive but sufficient to activate auditory responses in sensitized individuals. Under this model, the industrial source doesn't have to be loud enough for most people to hear. It just has to be present enough to trigger a disproportionate perceptual response in the 2 percent of the population whose auditory systems are tuned to those frequencies.
The cost to people who hear it
The Hum is not a curiosity for the people who hear it. It has driven at least one person in England to suicide. Others report chronic insomnia, headaches, nausea, nosebleeds, and diarrhea. In Largs, Scotland, residents moved away. In Windsor, the 22,000 reports to officials in a single night reflected a community that had been sleep-deprived and frustrated for months. The Hum is a quality-of-life crisis that hearers often can't prove to their neighbors, their doctors, or their local government — because the person standing next to them in the same room, at the same time, hears nothing.
This is what makes the Hum a genuinely interesting epistemological problem rather than just an acoustic one. It exists at the intersection of physics, biology, psychology, and infrastructure — a sound that may be real, may be internal, may be both, and whose investigation requires expertise in acoustics, otology, environmental engineering, and psychophysics, all operating simultaneously. The solved cases prove that external low-frequency sources exist and can cause the reported symptoms. The unsolved cases prove that the solved explanations don't cover everything. The biological evidence proves that the human ear can generate perceptions that have no external correlate. And the geographic clustering proves that biology alone doesn't explain the pattern.
Every proposed explanation accounts for some features of the data while failing to explain others. The researchers who study the Hum spend as much time arguing with each other as with the phenomenon.
What's still open
The Taos Hum, after 30+ years and a federal investigation, has no identified source. The Bristol Hum, after 50 years, remains unexplained. The unsolved cases share a feature that the solved ones don't: even with serious instrumentation deployed by serious researchers, no external generator could be located. Either the source exists but is too diffuse, too intermittent, or too unusual to detect with conventional equipment — or some fraction of Hum reports represent a perceptual phenomenon for which the geographic clustering itself remains the central mystery.

Two questions I'd love to hear from people who've actually experienced this. First: anyone here a Hum hearer? What does your experience match or contradict in the documented case profile — the indoor amplification, the nighttime intensification, the way earplugs sometimes make it worse? Second, for anyone with acoustics or otology background: is there a deployed instrumentation approach that could distinguish "external low-frequency source below the perception threshold of 98% of the population" from "internal otoacoustic emission perceived as external" in an individual hearer? Because that distinction seems like the central methodological problem and I haven't seen a clean experimental design that resolves it.

The Handbag Motif: Why does this specific 11,000-year-old symbol appear on every continent?
The video explores a specific visual pattern—a T-shaped container with a curved handle—that appears in stone carvings across civilizations that (according to the standard historical timeline) had zero contact with one another.
The Evidence Presented:
- Göbekli Tepe (Turkey): Carved into 20-ton pillars over 11,000 years ago.
- Ancient Mesopotamia: Carried by the Apkallu (sages) and deities as a "ritual bucket" or bandu.
- Mesoamerica (Mexico): Found in Olmec and Aztec carvings held by powerful figures.
- New Zealand: Featured in traditional Maori carvings despite the extreme geographic isolation of the islands.
