Ötzi, also known as the Iceman, is a naturally mummified man discovered in the Alps on September 19, 1991. He lived around 3300 BCE and is one of the oldest known natural mummies. His body was remarkably preserved due to the cold conditions, providing valuable insights into prehistoric life. The discovery of Ötzi revealed many artifacts, including a copper axe, a quiver of arrows, and various tools. These items suggest that he was skilled in hunting and had knowledge of metalworking. Scientists continue to study Ötzi to learn more about his diet, health, and the environment of his time.
