Let me just share one for now.
The pyramids were built by an advanced civilization, and the Egyptians, just like us, scratched their heads wondering who and how they were constructed.
If the Egyptians themselves didn’t know exactly who and how the pyramids were built, it is clear evidence that they had to rely on the knowledge and technology of an advanced civilization to construct them.
The architectural knowledge and technology of the Egyptians were limited to such an extent that it would have been difficult for them to build such massive and complex structures as the pyramids. During the construction period, the Egyptians used tools made of copper, and they were not capable of achieving the level of precision required for the construction of the pyramids.
Furthermore, the weight and mass of the stone blocks in the pyramids are so immense that they could only be moved and fitted using special technologies that the early Egyptians were not familiar with. The precise fitting and positioning of such a large quantity of stone blocks require mathematical and engineering knowledge that was beyond the reach of the Egyptians at that time.
