The truth of the underground world, giants are plotting to swallow humanity?

Until now, many people still believe that, in the underground of a certain country, there exists another civilization. That place gathers giants with advanced civilizations, gradually proving their existence and plotting to swallow up humanity.

One of the most shocking and chilling theories about the underground world is the story related to the Nazis. According to some secret documents believed to be from World War II, ancient maps have revealed a mysterious Nazi expedition to the center of the earth, in the cold and desolate region of Antarctica.

This theory suggests that a state-of-the-art German U-boat submarine made this crazy trip and planned to build a giant base underground. From there, some bold opinions suggest that some high-ranking members of the Nazis, even Adolf Hitler, are still alive and hiding underground, waiting for the opportunity to reappear and carry out their dark plots. Although there is no concrete evidence, this theory still haunts and stimulates the curiosity of many people.

Another theory about the underground world, which originated from ancient legends, is the story of the giant kingdom of Agartha. Believers of this legend believe that a world of giants and great cave cities exists under the surface of the earth. In the novel "The Smoky God" by Willis George Emerson, he describes the Agarthians as being about 12 feet tall and living at the center of the earth, an image that makes readers shudder and feel dizzy because of their size.

To reach the mysterious world of Agartha, legend has it that explorers must pass through special entrances scattered across the globe. These could be Mammoth Cave in Kentucky, USA, the Mato Grosso region in Brazil, or even caves and cracks in the earth’s crust scattered all over the world. Do these entrances really exist, or are they just portals to a mythical world in the human imagination?

Along with the theory that the Germans discovered a mysterious underground world in Antarctica, public opinion is equally stirred by the story of the Americans discovering an underground world in the Arctic. According to supporters of this theory, US Vice Admiral Richard Byrd – a famous explorer – once found the entrance to an alien civilization through a large crack in the Arctic. This story is said to be based on Byrd’s diary and accounts, although its authenticity is still controversial.

What's even more amazing is that when meeting Byrd, the aliens even said that they would help humans have an unlimited source of food when humanity was destroyed, a haunting and hopeful promise of an apocalyptic future.

In addition to legends about giants or aliens, Native American tribes such as the Oneida, Wichita, and Creek also believed that their ancestors lived underground. Some theories also suggest that many ancient Egyptian kingdoms with magnificent crystal castles lie deep underground, or even are home to a neutral alien race.

Not just a hypothesis, the underground city of Derinkuyu in Türkiye is a real construction. The city is 76 meters deep, with 20 floors, can accommodate 20,000 people, fully equipped with water systems, ventilation systems, and functional rooms. Derinkuyu shows that humans once built great underground cities, leading many to ask: is this a gateway to deeper mysterious worlds, where legends may be waiting to be discovered?

From ancient Nazi maps, the legend of Agartha to the living evidence of Derinkuyu, the underground world remains a fascinating and terrifying mystery, continuing to stimulate humanity's imagination and desire to explore.
