The Great Pyramid Mystery Solved?

How were the blocks of the pyramid raised to the top of 489th feet of the pyramid?
Using a machine that can lift?


. . . . . . . . .but how?


If Egyptians live on a primitive and ancient life, how is it possible to invent a lifting machine
from accessible materials around them wherein metals is not been discovered for structure
assembling?

The architects made their own theories about the making of pyramid:

It would be possible if they used the "Internal Snake Ramp"



The pyramid can be made if they used that ramp as the level increase.
The ramp is made as pathway of blocks.
The corner of the ramp is an open area so that when the workers
pull the blocks, the corner will be the staying area!


But.....the French team conducted some studies
and the theory of ramp doesn't exists in the pyramid!

Still....it is not yet been solved!
