For centuries, Egyptologists and geologists thought that the Egyptian pyramids were made of limestone blocks (up to 70 tons) that were quarried by chiseling limestone. Workers then carried those blocks up the pyramids on ramps. This building procedure was thought to be so superhuman that it made the pyramids become one of the Seven Wonders of the World. However today electron microscopes revealed that the blocks at the top have chemistries found nowhere in nature. Those blocks at the top must have been baked and then cast like modern cement (not chiseled from existing limestone) Learn More.
However 1400 years ago the Quran said that Pharaoh used baked clay (like modern cement; not chiseled limestone) to build their high rises:
[Quran 28.38] And Pharaoh said to his people: "I have not known a god for you other than myself; so Haman, light me a fire to bake clay so that I could build a rise high enough, maybe I see Moses' god whom I think is a liar."
How could an illiterate man who lived 1400 years ago have known that those high blocks were made from baked clay then cast like modern cement?
(The circumference of the circle is πD. So if the diameter is 10 units then the circumference should be 31.4 units. However in describing the temple the Christian Bible erroneously claims that the circumference is 30 units, making π = 3 (1 Kings 7:23))
