We know where the Egyptians got the limestone blocks for the Giza Pyramids; the quarries are right on the Giza Plateau. We know where they got the Tura limestone for the casing stones and have even found the landing point where they brought them across the river as the Tura quarries were on the east bank of the Nile. We know where the granite stones came from (Aswan, up river). There is no mystery in any of this.
What remains unknown is the type of ramp they used as any of the more obvious ideas fail because of practical or topographical reasons. They probably laid out the base and then began building both up and out at the same time raising the stones level by level as they did so. So there was no "ramp," per se.
The one piece of the puzzle that makes no sense is the "tombs and tombs only" approach of Egyptologists and this is a self-inflicted wound. The math simply does not work for building that structure in 20 years as a tomb for one man.
