At Puma Punku in Bolivia, you find andesite blocks cut with tolerances of 1/100th of an inch. Surface flatness that rivals modern machining. With bronze tools? The mainstream explanation doesn't match the physical evidence.

The Antikythera Mechanism is a 2,000-year-old analog computer with 37 bronze gears that predicted eclipses, tracked planetary positions, and calculated Olympic Games dates. The precision of the gears is extraordinary - nothing comparable exists for another 1,400 years.

The Baghdad Battery is a clay jar containing a copper cylinder and iron rod. When filled with acidic liquid, it generates about 1.1 volts. Dating to around 250 BCE, it predates Alessandro Volta's battery by 2,000 years.

From an engineering standpoint, the granite construction in the King's Chamber is fascinating. Granite's density makes it resonate at specific frequencies around 110-126 Hz. The precision of the chamber dimensions suggests intentionality.
