Tibetan
Tibetan inscriptions date back to the 7th and 8th century. The origin of the Tibetan script is somewhat unknown. There are a few places that are thought to be the origin of it, but no-one knows which yet. However the script's structure shows us that it's ancestor is the Brahmi script of India.
