The following are images of an ancient ostrich egg that was carved into a region of ancient Nubia including the Giza Mirs  carbon dated to circa 4,400 BCE or about 6,500 years old.  This would also re-date the Giza Mirs to an earlier time than previously taught by early 19th century Egyptologists as I have already proven via satellite geography showing the migration of the Nile from the causeway of the Mirs..
