His body was not moved by other people, or at least the evidence does not show that it was.

He was not formally buried.

He was not accompanied by grave goods.

He was just there, in the cave, in the cold and dark, as the centuries accumulated over him.

His mitochondrial DNA — the molecular inheritance from his mother and her mother and her mother before her, reaching back through generations to the ancient woman in whom haplogroup B first appeared — was preserved in his bones.

Preserved through thousands of years of cave conditions that were just barely cold and dry enough to keep the molecules intact.
