Progress takes pure imagination. Without imagination, America would never have come to sit on top of the world with a history shorter than a day by Ancient Egypt's standard.
Are Egyptians lacking imagination? ... I am not an anthropologist to answer that question, but We are lacking something!
A people who chose to live in mud houses for 5000 years and build a tomb that cost 40 billion dollars in today's money for the dead rotten corpse of their ruler must be unique in the sense of imagination! ...
No where in the annals of human history is this phenomenon documented other than in Egypt. Even in this our modern time, we still have a dead mummy sitting on our chest pretending to be alive, and an overwhelming majority of the populace still think it is alive and bow down to it!
