It's also worth noting that there are no hieroglyphs inside the Great Pyramids (which are supposedly said to be tombs), when the Valley of the Kings (an actual tomb) was caked in them.
Also, the only written text depicting the construction of the Great Pyramids, that I could find, is (again, supposedly) the Famine Stele. I find it highly questionable that there is only one text that tells us of the most notable construction of ancient Egypt's entire existence, and one of the most notable buildings to date. And not a single hieroglyph amongst the Pyramids' vicinity says anything about it either.
