While we can't radiocarbon date rocks, we can do that with other building material. From Wikipedia:
Mortar was used generously in the Great Pyramid's construction. In the mixing process ashes from fires were added to the mortar, organic material that could be extracted and radiocarbon dated. A total of 46 samples of the mortar were taken in 1984 and 1995, making sure they were clearly inherent to the original structure and could not have been incorporated at a later date. The results were calibrated to 2871–2604 BC.

- exe34 2y agocould you please highlight where you think the poster threw out Occam's razor? Probing the mortar seems to be to be a reasonable proxy for the age of the construction?
