About our
UFO Timeline

The UFO Timeline eras:

The UFO Timeline Project organizes sightings, cases, documents, and cultural milestones across clear historical eras to make patterns easier to see at a glance. Timelines span Prehistory (before 3300 BCE) and Ancient History through the Classical Era and Middle Ages, then Early Modern and the Industrial Age, into the Modern Era (1900–2000) and the Present Era (2000–today). Each era highlights notable reports, government actions, scientific studies, maps, and media that shaped public understanding, linking out to evidence pages, documents, and datasets. The goal is simple: give you a chronological, source-linked path through centuries of aerial anomalies so you can compare contexts, track recurring themes, and explore how technology, geopolitics, and culture influenced both sightings and explanations over time. Plus we also have a page for incidents outside time...
