i was wondering why the european was mummified and found in places along the silk road?

Yes, I heard of this. That is from a Germany research report, saying that the mummies found along the Silk Road hasthe DNA of Europeans. They are believed to be the Celts living in Northern Europe. They hiked to the Silk Road area 3000 years ago. Silk Road is just a business route between old Aisa and Europe. Because of the natural condition there was not good. There used to be high level civilizations in the desert area.

Well there is a popular story about how theres a lost legion of rome that traveled out there after the triumvirate crassus fought and lost against against parthian army, and abandoned them, he later died, but his legion lived on, some of the army made it to syria, but the rest is not for certain. the story is that the legion made it's way to china and served the chinese emperor. There is some dna evidence for this.
