The star Achernar was the southern pole star around 2650 BC, during the time of the ancient Egyptians.

‘According to some reports, the Step Pyramid [reportedly built as a tribute to Zoser's greatness in 2650 BC] is the oldest human-made structure in the world today. Zoser's Step Pyramid at Saqqara was an imposing edifice [200 feet tall], but it was built with relatively small, manageable blocks that five or six men working together could carry. Its internal chambers were structurally unsound.’
