The video discusses the concept of Pangaea, a supercontinent that existed when most of the world's landmass was united. Alfred Wegener, a German meteorologist, proposed the theory of continental drift in 1912, suggesting that continents slowly separate over time. Initially, his theory was not widely accepted due to a lack of a convincing mechanism, but he provided evidence such as the puzzle-like fit of South America and Africa and similar fossils found on both coasts. Later scientific discoveries confirmed that continents move continuously as part of tectonic plates. These plates, which formed over 4 billion years ago, are in constant motion. The video also speculates on how the continents might look in 250 million years.
