Intraterrestrial civilizations: “A world hidden from humanity” (Video)

It is possible that there is a totally unknown world under the surface. An inner land that expands across the planet through unexplored tunnels and caverns. The home of intraterrestrial civilizations.
There are thousands of stories of people who entered mines or caves who entered a world totally alien to ours. Where intraterrestrial civilizations live freely.
Intraterrestrial civilizations on Earth
Imagine entering a cave and, by chance, leading to a secret entrance that takes us to a fascinating mythical city. Where there is an altar with non-human figures, very similar to the idea we have of aliens.
An underground passage where you can admire the riches left behind by ancient ancestors or perhaps take you where other possibilities may exist.
Underground cities that have not yet been fully discovered, such as Shin-au-av or many others that, despite being known only by name, are all surrounded by great mysteries. Including the possibility that intraterrestrial civilizations inhabit them.
In Mexico there are 52 indigenous peoples, heirs of ancient pre-Hispanic cultures. One of them, the Maya, shone with great splendor in Mesoamerica for 3,000 years. Time that includes southern Mexico, Guatemala, Belize and part of Honduras and El Salvador.
This civilization left behind a vast heritage of advanced mathematical and astronomical knowledge that still stands out in its pyramids, palaces and temples. However, we still don’t know the dark story of its collapse.
What happened to them? While there are still some descendants among us, there will always be the mystery of why the vast majority disappeared from one moment to the next, perhaps to take another form of life?
Many claim that they descended into the depths of the Earth, fleeing the dangers that lay ahead on the surface. Now, the most important archaeological finds of the decade are discovering that truth.
A hidden Mayan world?
Guillermo de Anda, director of the Great Mayan Aquifer project, at the National Institute of Anthropology and History, reported that on March 4, in the Balamkú cave, hundreds of archaeological artifacts were found in honor of the Mayan “jaguar god”.
The cave was 2.7 kilometers east of the Temple of Kukulcan and was discovered in 1966 thanks to farmers in the San Felipe community. However, it remained intact for 50 years when an archaeologist decided to block the entrance.
In 2018, this site was rediscovered and it was determined that it had not been looted as access to it was difficult. The pieces found at the site were surprising, although some vases were fragmented, perhaps by the passage of time or due to some ritual.
So far, 200 incense burners have been discovered, as well as miniature braziers, vases, bowls, spirals and metates.
These pieces can be from the Late Classic, between the 7th and 8th centuries, and from the Terminal Classic, approximately in the 9th and 10th centuries of our era. Being used at least during these periods, they are part of 7 offerings dedicated to the image of the rain god in the Mayan cosmovision.
So far, about 460 meters of four have been explored, in addition to having to enter through cracks of just over 40 centimeters in circumference.
This shows a very deep meaning; With this discovery, the Mayan people left behind a mystery that may never be revealed.
Why did they leave these objects in such remote places, practically impossible to reach? It is possible that it is the entrance to a world hidden between mountains and caves, far from everything we know where intraterrestrial civilizations exist.
