Who Actually Built the Pyramids
What we know about the builders
The workers who built the Giza pyramids were Egyptian. We know this because we have found their remains, their tools, their villages and their administrative records. Excavations of workers' settlements near the pyramids, carried out since the 1990s, have found bakeries, breweries and housing arranged by work crew.
Archaeological and documentary evidence points to organised, conscripted labour rather than slavery, as the ancient Greeks assumed. Work-gang graffiti in the pyramid's relieving chambers includes crew names built around Khufu's name, suggesting a culture of pride in the work. Skeletons from the workers' cemeteries show injuries consistent with heavy labour, including healed fractures that suggest medical care.
The engineering
The ancient aliens hypothesis holds that ancient Egyptians could not have built the pyramids without extraterrestrial assistance. This argument rests on a misunderstanding of what ancient Egyptian society was capable of, combined with a vague sense that the pyramids are too impressive to be explained by human effort.
Experimental archaeology has demonstrated repeatedly that the core engineering challenges of pyramid construction, moving large stones, cutting them accurately and stacking them, are solvable with the tools and labour available to ancient Egypt. The logistical challenge was enormous but not impossible: Egypt had a large organised state capable of coordinating thousands of workers.
Why the alternative explanations fail
The ancient aliens hypothesis has no positive evidence: no alien artefacts, no anomalous technology, no accounts in any Egyptian text of non-human builders. It relies entirely on the argument that humans could not have done this, which the archaeology directly refutes.
The hypothesis also insults the engineering skill of ancient Egyptian society, which was demonstrably sophisticated in mathematics, astronomy, materials and project management. The evidence of that sophistication is in the pyramids themselves.
