The Nebra disc is currently the oldest known representation of the celestial sky. This was a phenomenal archaeological discovery that took place on Mount Mittelberg, near Nebra (Saxony-Anhalt, Germany) during 1999. It has been shrouded in mystery and controversy since its discovery and it has even been suggested that its design is of extra-terrestrial origin.
Although there has been concern raised that the Sky Disc is a fake, multiple tests have revealed that it is authentic – an opinion held by the majority of researchers and archaeologists.
Did the ancients have much more advanced technology than we know. For example, within the Temple of Hathor, which is part of the Dendera (Tentyra) Temple Complex in Egypt, are a series of carvings that many people believe depict the sophisticated use of electricity to generate light.
