It's certainly cinematic to show Jews working on the pyramids, but Jews haven't been "pirating" credit for them from Egyptians.
Still, the articles I've seen in news media (nearly all of which are the same AP story) don't explain how the newly uncovered skeletons show that workers were paid and not slaves (even though they weren't Jews). Proximity of the burial shafts, and the presence of beer and food there, say Egyptologists, are the key. But studies on the skeletons apparently reveal signs of back-breaking work and early demise. I'd really like to learn more, and explore why Egyptian archeologists come across so emotionally about what should be an objective, careful and strictly scientific analysis.
