Imagine discovering one day you'd been living on top of a 'shrine' of human bones.
That was one man's predicament after a group of YouTube cave divers made a horrifying find underneath his property.
Identical twin brothers James and Edward of ActionAdventureTwins regularly post on their channel to share how horrifying exploring underground caves can be.

Viewers are often shocked at how brave the siblings are taking a look inside America's most dangerous caves.
In a YouTube video from last month, they are joined by Davis (@CaveChronicles), as they explore a property belonging to a family for 50 years, who weren't aware of massive sinkhole below.
After taking a deep dive, the group came across a load of bones, as one of them goes: "Dude there's so many bones down there."
"There's bones everywhere," the other agrees.

"This thing's a death trap look," they added.
Once they got even lower, the divers noticed what they believed to be 'human bones', which were lying around.
There appeared to be a 'little shrine' of them with what looked like a human's skull.
"I don't know it's awfully round," the YouTuber added.

Taking to the comments section, some viewers were adamant that the bones once belonged to a living person.
"My girlfriend and I are watching from Canada! We’re both paramedics, definitely a human femur and a human cranium. Thanks for making the awesome content!!" one comment read.
Meanwhile, Davis himself insisted that the bones were human.
"Those were definitely human bones. The landowner said that land was a hotspot for Native American tribes and they have found over 200 arrowheads there over the years," he said.
"I got a call from the Division of Archeology this morning. They are Native American from the Woodland period. Most likely 500-1000 years old but could be up to 3000 years old."
Another person also added: "As for bones... yes those appear to be mostly human bones.

"You have the top of the skull, or 'skull cap' then to the right a partial pelvis, I think human though the rounded top area called the 'iliac crest' is really large!
"Male and female pelvis's are shaped different - the female round in the centre for childbirth, the male more narrow.
"It would be hard to say without measurements and a better evaluation.
"The two 'long bones' could be human, but the largest femur bone (upper leg bone) is pretty darn large for a human (this would be from hip to knee with the top rounded ball that fits in the pelvis, or 'hip socket').
"Maybe femur just looks huge in the video, or the person was huge!"
