how sure are you that it was the Egyptians who built the pyramids? well yes, if you go to Egypt and read through their libraries, sasabihin nila proudly that they built it.

Egypt even formed alliance with Middle-East Syria in the 70's and participated in the Egypt-Syria vs. Israel war. Modern Egyptians consider themselves Arabs. Why is this so? Most Arabs are in the middle east, Egypt is in Africa. what's the connection? unless they're sourgraping on the idea that Moses' people built the pyramids as claimed by the bible.

It is a well known fact that even with our advanced building/engineering equipments of today, we can never replicate the perfect structure of the pyramids. That's one of the mysteries of the pyramids until modern times.
