View of a wall at the "Cave of the Beasts" is seen in Gilf al-Kebir some 550 miles (900 km) southwest of Cairo, near Egypt's south-west border with Libya and Sudan in this undated photograph.

Rudolph Kuper, a German archaeologist, said the detail depicted in the "Cave of the Beasts" indicate the site is at least 8,000 years old, likely the work of hunter-gatherers whose descendants may have been among the early settlers of the then-swampy and inhospitable Nile Valley.
