Where strange underground tunnels connected to each other came from all over the world

 Ancient civilizations continue to be a fascinating topic of study, especially because of their advanced technology, architecture and culture. One of the most intriguing legacies of antiquity are underground tunnels stretching across different continents. Who were their creators, what were their functions and how were they created?

Underground tunnels are networks of underground passages used for various purposes. They differ in shape, size and depth. Some of them were built in antiquity, others were built by later civilizations.

Our planet is intersected by a network of ancient tunnels, which supposedly also extends to the bottom of the oceans. These enigmatic structures appear to have been precisely laser-cut into the ground and have smooth glass walls. The oldest tunnels were discovered in 1965 by the Argentine ethnologist Juan Moricz, their age is estimated at almost a million years.

Researchers have conducted expeditions in various parts of the world, but most of them are still unexplored. Ancient underground tunnels are believed to pierce the North American continent, connecting it to Europe and East Asia. In some places, such as under Mount Shasta in California, Tibet or under the pyramids on the Giza Plateau, there are key intersections of these tunnels - junctions. The node of the ancient underground system is also located in the Caucasus region and in Crimea.

There are many theories about the purpose for which underground tunnels were built. Scientists suggest that they could have been used for defense, sheltering people in the event of wars or natural disasters, transporting people and goods, and even for religious purposes or as a place to store valuables.

There are theories that our planet is covered with a system of ancient tunnels created by a highly developed civilization that disappeared from the face of the Earth. Another theory suggests that the tunnels were created as a preparation for nuclear war. A study by a group of French experts has found that some of the craters believed to be meteorite impacts may also have been created by nuclear explosions.

Recent research suggests that tunnels and underground labyrinths may not just be the work of ancient civilizations, but a real inhabited world. Some scientists argue that these structures may have been created by a technologically advanced population that predicted global catastrophes and decided to settle down in a safe place. Another theory suggests that these may be the bases of aliens who have long been in contact with the secret services.

Despite the discovery of underground tunnels on different continents, scientists still have difficulty determining their true purpose. Most theories are based on guesses. The most intriguing question is how ancient civilizations could create such advanced and extensive underground structures without the use of modern technology. Some scientists suggest that they used technologies that have been lost over time.

The underground tunnels of ancient civilizations are a fascinating field of research that provides us with as many answers as questions. Who and why created these ancient underground structures? What were their real functions? We can only guess what other secrets lie hidden in the depths of our planet.
