Could there be another advanced civilization underneath our feet?

If creatures exist under the surface of our planet, they would not reside in volcanic rock, but rather in advanced spacecraft that are capable of generating the necessary conditions for life to survive. Are tectonic plate changes a result of their actions, or are they a natural feature of the Earth?

Theories concerning the Hollow Earth often feature a central sun, aliens, and mythical underground cities and civilizations that some open-minded individuals believe may bridge the gap between science and pseudoscience if physically uncovered.

This notion of underground regions looked debatable in ancient times, and it became coupled with images of ‘places’ such as the Christian Hell, the Greek Hades, the Jewish Sheol, or the Nordic belief of Svartalfheim.

However, with both sides of the Arctic and Antarctic areas melting at a rapid pace in current times, the truth behind this conundrum and its symbolic linkages to other origin or creation myths in the history of humanity’s journey on planet Earth may soon be disclosed.

Our globe, according to the Hollow Earth idea, is either completely hollow or has a large internal area. There are rumored to be races that live in underground cities under the surface of the Earth.

These subterranean inhabitants are frequently more technologically sophisticated than we humans on the surface. Some think that UFOs are not from other planets, but are fabricated by strange beings from the inside of our planet.

Throughout history, some people have claimed to have seen these enigmatic beings from the Earth, and some have even written extensive records of their encounters or even books about how they were greeted and advised.

An intriguing depiction of such an encounter comes from John Cleves Symmes Jr, an American officer, merchant, and speaker who pioneered the notion of entrances to the poles’ inner world.

Symmes stated that: “The Earth is hollow and inhabited within; it contains several solid concentric spheres, one within the other, and it is open at the poles 12 or 16 degrees; I vowed my life in favor of this reality, and I am ready to explore the hollow if the world would support and help me in the attempt.”

The planet, according to Symmes’ Hollow Earth hypothesis, is made up of five concentric spheres, the largest of which is our outer earth and its atmosphere. He estimated the Earth’s crust to be around 1000 miles deep, with an Arctic opening about 4000 miles wide and an Antarctic opening about 6000 miles wide.

He said that he was able to access this underground world because the curving of the rim of the polar apertures was gradual enough that he could enter the ‘inner Earth’ without being aware of the route.

He claimed that the globe would be flattened at the poles due to the centrifugal force of Earth’s rotation, allowing sufficient entry into the ‘inner Earth.’

Symmes also stated that the inner surface of his Hollow Earth’s concentric circles would be lighted by sunlight reflected off the outer surface of the next sphere and would be inhabited, being a “warm and prosperous place, supplied with thrifty plants and animals if not mankind.”

He eventually determined that the Earth, as well as every celestial orbicular body that existed in the cosmos, visible or invisible, and that participated in whatever degree of planetary type, from the tiniest to the biggest, are all established, to varying degrees, in a compilation of spheres. Symmes wasn’t the most effective professor.

As a public speaker, he felt uneasy. Nonetheless, he hung on. He began to make followers, and his ideas began to take shape in the minds of the people. Symzonia, a novel he wrote in 1820, is widely linked with him.

It tells the story of Captain Seaborn, who sailed out for the South Pole in 1817 to verify Captain John Cleve Symmes’ hypothesis of an interior universe.

Afraid of his crew’s attitude, he does not completely notify them of his goal, instead of recruiting them for a commercial expedition in the South Seas. The team discovers an interior continent named Symzonia after Symmes, where the new planet looks to be a garden of paradise, including the following elements:

“Gently rolling hills within an easy sloping shore, covered with verdure, checkered with groves of trees and shrubbery, studded with numerous white buildings and animated with groups of men and cattle, all standing in relief near the foot of a lofty mountain, which raised its majestic head above the clouds in the distance.”

The internals are regarded as a peaceful race, with authority derived from the people. They were governed by a “Best Man” and a council of one hundred people who were chosen for their humble and excellent worth. The internals’ most basic quality was their modest way of life since they scorned financial gain and sensuous pleasures.

They lived equally, without a desire for money or sexual pleasures, and produced just what was required by society. Society is defined as striving for the common benefit and prosperity of all of its members.

This justice extended to their food as well, since they were all vegetarians. Because of the disparity in the two species’ ideas and ideals, the “Best Man” orders Seaborn and his crew to depart this paradise within the Earth, as described:

We looked to be of a race that had either fallen completely from virtue or were very much under the sway of our nature’s darkest desires.

Even if Symmes and his pupils were unable to provide conclusive evidence for their assertions, there must be more than a grain of truth in it because innumerable individuals have glimpses of this inner location and receive spiritual instruction from it.

In our present state of knowledge, we realize that the planet Earth is riddled with mysteries that have yet to be solved. The Earth is claimed to be about 8,000 miles in circumference, although the deepest excavations ever tried barely reached half a mile below the surface.

As a result, we are incredibly unaware of the nature and structure of the innards of this immense mass that is the Earth, and we may stay so unless those intraterrestrial entities (assuming they exist, of course) decide to take the first step towards us.
