📖 เนื้อเรื่อง

The Construction of the Great Pyramid of Giza has long fascinated scholars, and many theories have been proposed to explain how ancient Egyptians moved and lifted massive stone blocks. One prominent theory suggests that the pyramid was built using a straight, external ramp. Proponents argue that such a ramp, made of mudbrick and limestone chippings, would have allowed workers to drag blocks on sledges up the pyramid's face. This method is plausible because it requires only simple tools and a large workforce, both of which were available. Additionally, the ramp could be extended and heightened as construction progressed, providing a continuous pathway. Finally, archaeological evidence, such as remnants of ramps at other pyramid sites, supports the feasibility of this approach. Therefore, the external ramp theory remains a convincing explanation for the pyramid's construction.

The external ramp theory, while popular, faces serious challenges. First, a straight external ramp would have been enormous—reaching nearly a mile in length and requiring more material than the pyramid itself. This would have doubled the construction effort, making it impractical given the limited time and resources. Second, the ramp's slope would have become too steep as the pyramid grew taller, exceeding the angle at which workers could pull heavy blocks. To maintain a manageable slope, the ramp would need to be extended far beyond the pyramid's footprint, disrupting the surrounding landscape and requiring massive earthworks. Finally, while ramps have been found at other sites, they are typically short and used for smaller structures, not for monuments of the Great Pyramid's scale. More recent evidence suggests the use of internal ramps or water-based lifting systems, which better explain the precision and speed of construction. Thus, the external ramp theory is not supported by practical engineering and archaeological considerations.
