Egypt discovers what may be oldest human footprint

Egyptian archaeologists have found
what they said could be the oldest human footprint in
history in the country's western desert, the Arab
country's antiquities' chief said on Monday.

"This could go back about two million years," said
Zahi Hawass, the secretary general of the Egyptian
Supreme Council of Antiquities. "It could be the most
important discovery in Egypt," he told Reuters.

Archaeologists found the footprint, imprinted on mud
and then hardened into rock, while exploring a
prehistoric site in Siwa, a desert oasis.
