Semitic Consonantal Script on Cave Walls at Wadi al Hol Southwestern Sinai & Serabit al Kadim Near Luxor on Nile River

Translate:

Words of the Semitic consonantal writing system (“proto Sinaitic”) used by the ancient Hebrews and by the Canaanites (who learned it from the Hebrews) were discovered in southwestern Sinai near the Red Sea at Wadi al Hol, and westward into Egypt on the Nile near Luxor at Serabit al Kadim, indicating that what would be called Tifinagh (phonic) writing of the Berbers etched onto North African cliff faces and cave walls had been brought overland by Canaanites (and Hebrews?) toward the end of the Ice Age.
