No kidding, I did these same calculations a few years ago. Egyptology is a hobby. Don't forget, the whole outside of the pyramid was covered/cased in polished limestone after the blocks were laid, so thats even MORE time needed. personally, I think the pyramids are much older anyway, and sumerian writings seem to confirm that.

The last I heard about attempts to date the pyramids was when that little robot shaft-climber brought back TV images of a piece of wood - which can be carbon-dated, unlike stone. But the Egyptian government refused permission to retrieve it, since the last thing they wanted to do was risk the possible discovery that the pyramids are far older than Egyptian civilization. Science doesn't mix well with politics.
