Ethiopia is one of the world's oldest countries; its Rift Valley may be the location where the ancestors of humankind originated more than four million years ago. With a population of 67 million people today, it is the third most populous country on the African continent after Nigeria and Egypt. It is the source of 86 percent of the water reaching the Aswan Dam in Egypt, most of it carried by the amazing Blue Nile. Ethiopia offers major historical sites such as the pre-Christian palace at Yeha, the stele and tombs of the old Kingdom of Axum, and the rock-carved churches of Lalibela.
