Rollers were used instead of wheels when carrying bricks for the construction of the pyramids because the terrain was often uneven and sandy, making it difficult for wheels to function effectively. Rollers, typically logs or cylindrical stones, allowed workers to move heavy loads with less friction and more stability. Additionally, the technology for building effective wheeled vehicles may not have been fully developed at the time. Using rollers enabled a more efficient transport method suited to the materials and conditions present in ancient Egypt.
Constructing rollers at the base of a building helps to reduce the impact of seismic forces during an earthquake by allowing the building to sway and absorb the energy.

It is no longer a matter of 'theory'. It is now fairly precisely known how the ancients built them, how they cut the stones, how they transported them to the building site and how they got them on top of each other. As to the last point: they threw up an earth wall next to the wall they were building in the form of a ramp, and using tree trunks as rollers, pulled the stones up to the top of the ramp which was then as high as the top of the unfinished pyramid. Finally they removed all the earth ramps and left the pyramid standing free.
