People love to think of history as a collection of established facts, but that’s far from reality. Even after decades or centuries of research, some of the biggest questions about the past still don’t have clear answers. Archaeologists, historians, and scientists continue to debate everything from famous deaths to the true purpose of ancient monuments, and new discoveries sometimes raise even more questions instead of settling them. While some mysteries may eventually be solved, others have resisted every attempt at explanation.
