We don't know about the absolute dating in this site.
This site was abandoned for so long and perhaps forgotten.
The columnar joint is imported from another region,
from another location.
We are very surprised that this site consists of two cultural layers.
The first layer on the surface, it's from 500 BC.
But at four meters depth,
we found another cultural layer.
It is from 5,200 BC.
It is very surprising. We are very shocked.
It is very old.
I'm not really sure about the function of this site.
However, we've still not found a skeleton or human bone,
so this is not a burial site.
Perhaps it is for ceremonies or rituals.
They are natural, but the position now is not in the natural position.
-And normally vertical. -Vertical, yes.
-That's right. -And here it's laid on its side.
-Also, it's not cut like this. -Yeah.
Here, all is cut into one or one-and-a-half meters.
The natural position, there is no ground mass in between.
It will be very tight together.
But here, in between these columnar rocks, there is a mortar
-that holds them together, like cement. -Yeah.
The thickness is, like, five centimeters, and it's very consistent.
Yes. Yeah.
Yeah.
It's not the same shape of pyramids
like Mayan or Giza pyramids.
Yeah. But it has circular features.
So, we have three methods here.
-The GPR. -Yeah, that's ground-penetrating radar.
-Ground-penetrating radar, yes. -Yeah.
-And resistivity tomography. -Yeah.
And also the seismic tomography.
We're going to do the ground-penetration radar,
the GPR surveys.
We chose the frequency of 40 megahertz to penetrate down to 30 meters.
It has a seismic velocity of about 200 meters per second.
That's a void.
-A void. An empty space. -Empty.
Yes, as you see here, it's rectangular.
-And the spot is just right… -Yeah.
-…because in the center of this site… -Right.
…beneath the Terrace One, there is also a chamber…
…connecting to this chamber
beneath the second terrace.
When we see these chambers…
-Yeah. -…three chambers,
it's just like, we were amazed.
Okay. Layer four could be before 20,000.
-Could be before 20,000. -Very old.
-I think we know little about our history. -Right.
I think we miss a big thing here.
-They are still not accepting it. -Right.
I regret because archaeologists,
or any other researchers, just stop researching.
If we could prove clearly,
and accept there is advanced human cultures before 11,000 BC,
that will be a big step.
