Life generally exists on Earth, or has now expanded into outer space as well (call the ISS to the Moon that humans have visited). However, there is a belief that there is a city on Earth called Agartha. Agartha is called the place of beings called Yakjuj Makjuj.
Agartha is claimed to be a city or kingdom that is on Earth and inhabited by alien beings with advanced civilizations. This legend arose because in ancient times, people believed that the Earth was empty and filled with people of different races.
Although it is said that the physical stature of the creatures in Agartha is not much different from humans living on the skin of the Earth, Agartha is believed to be more intelligent and life there is more harmonious.
Agartha is said to be often mentioned in several religious teachings. Some believe that the Agarthas are Yakjuj Makjuj or Gog Magog in Islam, Christianity and Judaism. Well, if we discuss it scientifically, this belief seems to be supported by the 'Hollow Earth' theory.
Hollow Earth is a theory from Edmond Halley, an astronomer and geophysicist who says that the Earth may have a depth of up to 800 km and consists of two round shells and a core. Between the plates, there is a vacuum.
This theory was supported by John Cleves Symmes Jr in the 19th century. Symmes believes that the north and south poles each have holes that can lead humans into Earth, as stated in the article reviewed at Atlas Obscura.
Even so, the teachings of modern science refute this theory. Geological researchers based on research say that the Earth's surface to the core is 6,371 km. Even though Earth's excavation is not deep enough to be able to prove in detail the contents beneath the Earth's surface, in 2013, geological researchers found information that the Earth's core has a temperature of 6,000 degrees Celsius or 1,000 degrees hotter than the surface of the Sun.
But yes, even if there are humans on Earth, can they survive the extraordinarily hot temperatures? If so, surely his survival ability is extraordinary. So, what do you think?
