Lost Continents (theory)

The "Lost Continents" theory suggests that throughout Earth's history, landmasses have existed and then vanished due to geological processes like tectonic shifts and erosion. Proponents propose that ancient civilizations or large continents, such as Atlantis or Lemuria, once existed but are now submerged or fragmented beyond recognition. These ideas often blend scientific observations with speculation, aiming to explain missing land or ancient myths. While mainstream geology supports continental drift and plate tectonics as explanations for Earth's changing surface, the concept of entirely lost continents remains speculative, lacking strong evidence within the established scientific framework.
