What is cave exploration?

Cave exploration is commonly called caving, and a cave explorer is called caver. It started in Europe at the end of the 19th century, and now it is a sport that people from all over the world, from children to adults, mainly in Europe and the United States, enjoy. To describe the charm of caving in one word, it is a search for the unknown. With the development of satellite technology, it is said that geographical exploration has already ended, and the cave is said to be the last frontier left on the ground. The desire to explore land with no footprints may be one of the starting points of life that humans originally have.
