Ancient Egypt...and we still do not have a clue.

It is truly amazing and truly amusing with all of the engineering know-how of today ...with all of the collective knowledge of today...with all of the computers and computer wizards of today...we still do not know how the ancient Egyptians, from the continent of Africa, built the pyramids, the sphinx, the obelisks, the major structures, and the hyperstyle hall at Karnak, and the city of Luxor.
BTW...It is not "taught" today as it should be taught today, but last I checked Egypt was then...and is still...on the continent of Africa...and is not now...nor has Egypt ever been located in Europe.
