In this episode of The Big Picture, we dive into the deep-time reality of cataclysmic Earth events — the kind that reshape continents, erase civilizations, and leave behind scars mistaken for slow erosion.

Through satellite imagery, megaflood analysis, and overlooked geological features, we explore how modern science may be misinterpreting the largest and most rapid transformations in Earth’s surface history. What if the most important chapters in human prehistory are buried under debris fields, glacial till, or eroded river basins?
