The Ancestral Myth of the Hollow Earth and Underground Civilizations
Countless stories, myths, and legends are told about underground cities and subterranean c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ spread through a vast network of interconnected tunnels across the planet.
There are many rumors surrounding these underground portals. We have only to remember the mysterious stories that revolve around the tunnels and galleries of the Cueva de los Tayos en Ecuador, or stories about entrances to underground worlds, supposedly located in the Andes, the Himalayas, the Gobi Desert, Turkey, and even below the Sphinx of Giza
.The Hollow Earth Theory and an Expedition to the Arctic
The Hollow Earth theory states that the Earth is a hollow planet with ancient entrances to the subterranean world scattered throughout it, including near both polar caps. This theory has been reported since ancient times and scientists such as Edmund Halley have defended it throughout history.
From 1818-1826, the American John C. Symmes passionately supported the theory as well. According to him, there was a subterranean world inside our planet illuminated by a tiny sun, and that included mountains, forests, and lakes.
