While some ancient sites display unusually high radiation levels and vitrified stones—rocks that appear to have been melted by extreme heat—there is no credible evidence to support the theory that nuclear wars occurred in ancient times. Proponents of this idea often point to ancient texts, such as parts of the Mahabharata, which describe catastrophic events resembling modern nuclear explosions, including intense heat, blinding light, and widespread destruction. These descriptions have fueled speculation that ancient civilizations may have possessed advanced technology, possibly even nuclear weapons.
Archaeological sites like Mohenjo-Daro in present-day Pakistan are frequently cited in these theories due to findings of skeletons with high radiation levels and what some interpret as blast damage. However, mainstream scientists attribute these phenomena to natural causes, such as volcanic activity, meteor impacts, or conventional warfare, rather than ancient nuclear technology.

No physical evidence of nuclear reactors, weapons, or the infrastructure necessary to produce them has ever been discovered in ancient ruins. While prehistoric nuclear wars are a fascinating concept in speculative history and science fiction, it remains unsupported by the scientific community and is considered highly unlikely.
