Just How Old are the Pyramids? Egyptologists debate

Exactly how old the pyramids are has been the subject of discussion for many years. Egyptologist estimates are consider to be accurate by many in the field within about 100 years, but recently Egyptologist Kate Spence has suggested that the Great Pyramid at Giza was constructed in 2478 B.C. Her estimate is about 75 years older than the commonly accepted estimate. She proposes that the north/south orientation of the pyramids were established by aligning them with two stars. Because the earth's axis wobbles over time, the orientation of the two stars changes slightly over time. Spence proposes that the slight differences in the alignments of the pyramids can be used to develop an independent estimate of when they were constructed.
