Actually, until the Romans came the Germans didn't even have a written language and lived in pig $hit. In the ensuing 1800 years, they developed art, science, culture, and theology that was enviable.
However, the last 200 years the Germans have slowly been reverting back to their ancient primitiveness. The height of this was the Nazis, which totally rejected their Judeo-christian heritage and helped accelerate German De-evolution that has progressed to this day. Almost to a man, Germans totally reject Jesus Christ while accepting Soviet Atheism and/or Islam.
When people lose their Judeo-Christian beliefs and ethics, they revert back to what they were in their pre-Christian times, i.e., pagans.
