“Check the story from Genesis. He didn’t use a damn pyramid.”
Well, that ends that discussion. If it was one. My point was that it may or may not have been original constructed and re-purposed for a variety of reasons, none of which might be known definitively to any of us. Including you.
Don’t take that the wrong way. The Great Pyramids were monuments to men who viewed themselves as God not granaries.
The bible paints a realistic picture of what Joseph did. He stored the grain throughout the land and then gouged the populace during the famine. The windfall to the Pharaoh was substantial.
