Egypt is a country in Africa and it was the home to people, known as Egyptians.
During the 2012 apocalypse, Egypt was hit by massive earthquakes, and was swept by a megatsunami during the Worldwide Flooding. It remained flooded for 27 days until the global floodwaters began to recede and the entire African continent had risen, becoming habitable. This made Egypt, and Africa, not to suffer extreme damage.
This allowed the 2012 survivors (human and animal) on board the Arks to begin a new life and rebuild their species at the Cape of Good Hope.
