So apparently in about 2007, some scientist and researchers discovered that the stones of the pyramid were not carved stones, as it was thought for many many hundreds years before. The idea that those stones were carved, was even portrayed in one of the Western movies. NOW, they found that the 'stones' were actually 'made'. Meaning in those times, people were already making cement. And for a long time, they thought the Romans were the first one to invent cements for buildings.
This comes as a very big surprise for scientists. Some others are still unable to accept the fact, for they have been holding on to the idea that it was indeed carved limestone - even though they are unable to explain, how the people of those times could have carried these carved stones weighing tonnes, up to the top of the pyramid.

Meanwhile in the Qur'an unchanged from 1400 years ago, it is mentioned:
Moses said, "My Lord knows best who it is that comes with guidance from Him and whose end will be best in the Hereafter; certain it is that the wrong-doers will not proper."
Pharoah said "O Chiefs! no god do I know for you but myself; therefore O Haman! light me a (kiln to bake bricks) out of clay, and build me a lofty palace, that I may mount up to the god of Moses; but as far as I am concerned, I think (Moses) is a liar!"
And he was arrogant and insolent in the land beyond reason, - He and his hosts; they thought that they would not have to return to Us!
Al Qasas 28:37-39
