In terms of the erosion, doesn’t wind erosion on raised surfaces behave very similar to how water erosion on shores behaves?
Since both are just fluids brushing up against surfaces, and the fact in the desert the wind will have a lot of silica dust in it, it stands to reason the wind currents around the pyramid would have very similar erosion patterns to water on a shore.
Fluids are fluids, air doesn’t behave to dissimilar from the ocean, and wind is not to dissimilar from water currents in terms of the physics.
Silica dust will kick up off the nearby dunes, carry in the wind, but due to its weight it’ll be less likely to erode higher elevations. So the tip top of the pyramid is high enough up sand in the wind won’t reach it as easily so it erodes way slower.
Much akin to how waves crash on a coastline, water has weight so the higher an elevation is, the less and less sea spray it gets hit by, so it erodes slower.

That, and the pyramids were stripped for building materials later on. Lower levels were easier to access, so people didn’t generally bother going all the way to the top, except for the ones with gold covered peaks.
Not to mention, according to the Bible the world was only flooded for a few months. I’m not an expert on erosion, but this guy definitely is dumber than me.
Also even going with the flood theory, pretty sure Egypt comes after Noah even in the Bible itself >_>;
The world did flood when humans were around (most cultures have great flood stories from ancient times), but that was way way before Egypt.
Amusingly iirc the Nile nearby however is a great example of proof the earth once was covered in ice the melted and flood, as I believe it’s a giant striation or whatever the term is, huge gouge left behind by receding ice, no?
That’s why it’s so big and runs so far, it’s ancient from countless years of erosion and meandering after being carved out during the ice age.
Genesis is pretty clear that Egypt came after the flood. Noah had sons with him. One of them, Ham fathered Africans. Noah’s grandson Mizraim was the father of all Egyptians.
Some early Christians reconciled that with the obvious age of the pyramids by guessing that the pyramids predated the flood and modern Egyptians were simply a new population, but no one’s seriously argued that in literal millennia.
With no background in the subject my assumption is that it would be more punctuated or abrupt for water. However I don’t think it would be two lines for the troughs vs crests. I’d assume it would just be general water height. The reason is that water would obviously erode much quicker than air. Add on that the water level is much more definite than air and how high dust would get within the air to increase erosion.
Again, no background expertise. Just what I’d guess in the given subject in general.
I’m going to throw a little bit of a curveball at ya. Most of the damage to the pyramids in Giza isn’t from erosion. They were originally covered in white limestone and the tops were capped in hammered gold. An earthquake sometime in the early 1300s began dislodging the limestone and from about 1600 to about 1800 a quarry was established in Giza and the gold and limestone were removed.

I thought the Roman’s started taking the gold like 2000 years ago?
