en Cuevana 3. Documentary tells the story of Germany's origins from the Carboniferous period to the present day. It leads from the highest Alpine peaks to the rugged North Sea coasts - from the craters of the Eifel to the river labyrinth of the Spreewald. Back then - around 300 million years ago - giant dragonflies, for example, buzzed through dozens of meter-high fern forests. In the course of the Earth's history, however, we also encounter dying dinosaurs, meet rhinos and elephants on the Rhine and come across what is probably the first human in Heidelberg. Later, the Neanderthals appear and suddenly disappear again - for reasons that are still unknown. And finally, modern humans gradually spread and began to shape their environment.
