Is that what Hancock said, or is that your assumption?
Not everyone here has read Hancock's books, and not everyone would agree with this conclusion. Is there a reason for this conclusion?

Why does it mean that?
Someone (you?) are presuming the general population lived and was buried in the immediate vicinity of all the monuments. Today, we easily associate burials and cemeteries with churches, and maybe castles, the church being the monument (in our eyes) that is surrounded by graves or has a cemetery next to it. Do you know of burials around power plants? Or around shopping malls, or government buildings, or skyscrapers, or any grand building that had a public function? When cemeteries are inside a city's limits, I think that was not the original intention. They were originally placed outside of the village and as the village grew, it eventually grew beyond the cemeteries. Do you know of any indigenous tribe that buries inside their village, which would be like burying in your back yard. Today it is the custom to bury in the city's cemetery, but we cannot assume this was the custom 4500 yrs ago or beyond. We should not project our customs onto those of ancient man. Just as we would not presume those buried in a church cemetery were the architects, engineers and laborers of the church.

As I understand, Hancock believes Khufu was the builder of G1 and the gizamids were built circa 2500 b.c.
It looks like you are discussing Hancock's theories, in which case you would have to exclude the great pyramids.
Basically you are saying...... the city's inhabitants lived and were buried at the base of all monuments worldwide and so their remains should be found. And the Egyptian pyramids meet this criteria, therefore the tombs at the base are those of the builders. If there are no remains found surrounding a monument, there is no evidence of a lost civilization.
Is the engineer of the Golden Gate Bridge buried beside a pier? Where are the laborers buried? Is the architect of Notre Dame buried beside the church? Why on earth would we assume it was a worldwide custom to bury the builders directly beside the monuments? The Egyptian pyramids are not tombs. Egyptology has demonstrated tremendous imagination in interpreting the surrounding tomb occupants to be those of the builders.
Besides, you're missing all the evidence of cosmic catastrophes.
