An "artifact" is an object made or used by humans, often of historical or cultural significance. Artifacts can include tools, pottery, clothing, and artwork, providing insight into the lives and practices of past societies. They are commonly studied in fields like archaeology and anthropology to understand human development and cultural evolution. Artifacts are typically found during excavations or in historical sites, and they help researchers piece together information about ancient civilizations. For example, artifacts from the Roman Empire can reveal details about their daily life, trade, and technology. Each artifact serves as a tangible link to history, enriching our understanding of human heritage.
