Ethiopia is the oldest independent country in Africa and one of the oldest in the world. What are believed to be the oldest remains of a human ancestor ever found, which have been dated as being some five million years old, were discovered in the Awash Valley in Ethiopia. This beats the discovery of "Lucy", a 3.2 million year old skeleton, who was unearthed in the same area in 1974. The Greek historian Herodotus, of the fifth century BC, describes ancient Ethiopia in his writings, while the Bible's Old Testament records the Queen of Sheba's visit to Jerusalem where "she proved Solomon with hard questions". Matters clearly went further than that because legend asserts that King Menelik - the founder of the Ethiopian Empire - was the son of the Queen and Solomon.
