I’m a fan of Eurasia myself, personally. It makes sense. There’s zero geographic boundary between Europe and Asia, unlike the Suez and Panama isthmuses.

The 6 continent model that merges the Americas into one is the one I absolutely cannot abide. There’s no reasonable argument for saying North and South America are one continent that doesn’t also include making Afro-Eurasia a single continent.

But this video touches on something a bit different from that debate. Which is around completely different types of continent models. There’s the “large landmass” one that we usually discuss in school. But also plate tectonics. Biogeographic realms. Cultural regions. And other ways of defining it besides, probably.
