Mohenjo-Daro, an ancient city located along the Indus River, was once home to over 30,000 residents. Archaeologists have uncovered perplexing phenomena at this site: inhabitants appeared to have died under unusual circumstances, with no clear signs of epidemic outbreaks or violent attacks. Even more astonishing are the traces of high-temperature heating found at the site, including a glass-like substance known as trinitite, which is typically produced by nuclear explosions. These discoveries have sparked speculation about ancient nuclear warfare, challenging our understanding of early civilizations. However, these pieces of evidence have yet to be fully substantiated, leaving many mysteries still unresolved.
