Who were the first Americans?

In this Stuff You Should Know episode, Josh and Chuck dive into the fascinating mystery of how the first people arrived in North America, challenging everything you thought you knew about early American history. They explore the rise and fall of the "Clovis First" theory - which held that big game hunters called the Clovis people were the earliest Americans around 11,200 years ago - and how new archaeological discoveries at sites like Monte Verde in Chile completely turned this theory upside down. The hosts discuss competing theories about ancient migration patterns, whether early peoples walked across a land bridge or sailed by boat, and why some of these early civilizations mysteriously vanished without a trace.
