What Archaeology Says

The capital of the Nabataean Kingdom (c. 400 BC–106 AD), Petra was a wealthy trading hub controlling spice and silk routes. The rock-cut facades were carved by skilled Nabataean craftsmen using chisels and mallets — tool marks are still visible. The city's sophisticated water system, including dams, channels, and cisterns, reflects advanced hydraulic engineering, not alien assistance.
