Why have historians and archeologists been unable to determine where Asia the huns came from?

Historians and archaeologists have struggled to pinpoint the origins of the Huns due to a combination of sparse historical records and the nomadic lifestyle of the Huns themselves, which left little in the way of permanent settlements or artifacts. Additionally, the Huns emerged in Europe during a time of significant migration and upheaval, making it difficult to trace their movements and connections to other groups. Genetic studies and linguistic evidence provide some clues, but the lack of written documentation from the Huns further complicates efforts to establish a clear origin.
