Final answer:
The statement is false. Scientists do not know exactly how Egyptian pyramids were built, but archaeological evidence suggests skilled laborers used ramps, ropes, and pulleys, reflecting advanced organization and engineering knowledge.
Step-by-step explanation:
False, scientists do not know exactly how Egyptian pyramids were built. While modern archaeology has provided substantial information about the organization of labor and materials used, the precise techniques employed in the construction of the pyramids remain partially understood. Archaeological findings suggest that the labor force consisted of skilled craftsmen and builders, likely supplemented by seasonal crews of conscripted peasants.
The method of transporting the massive stone blocks, each weighing about 2.5 tons, probably involved hauling them up ramps with ropes and pulleys, facilitated by a surface lubricated with wet silt. These engineering feats showcase the high level of organization, structure, and advanced knowledge of geometry and measurement that were present in ancient Egypt.
