Keeping up with the Egyptians: Building Pyramids

Its easy to see that building the Egyptian pyramids using a ramp would have been impractical and too labor intensive to make sense. And its doubtful to think they were built by aliens or giant people big cranes or flying machines. But how were they built? After years of pondering and running model after model through my mind I have come up with a theory that makes sense seems to answer all unreasonable questions and is clearly possible in their days using simple physics mechanical means common materials and skilled human beings. This plan uses 0.1 percent the energy needed to drag a stone up a ramp and to set a stone on top of the pyramid every two to three minutes putting the stone cutters to their limit.
