The Ancient Africans in Nabta around 6500 BCE built a "stonehenge". The Ancient Egyptians used Astronomy to support Agriculture Calendar.
This is actually a common misconception with many people who may not have ever seen the word. The proper spelling is Stonehenge and it is quite a marvelous sight.
The first "sighting" of Stonehenge was when it was built. Since that time it has remained in the same location, which has been common knowledge. It has never been lost or rediscovered.
