How did people lift the giant stones to make a pyramid

Not directly. But first you have to transport the stones from the stone mine on the place which is the hardest task. As for putting stones one on the other it is much easier, all you need is a half-spiral shaped undercarriage that you attempt to ow, but it turns the stone block to side, while simultaneously pushing it up. Try it with sugar cubes.

Is is also much more safer and energy efficient than simply lifting the block into air like we do it now with cranes. Cranes allow you to put things on different places inside and are faster than the rolling-on-side method.
