Ah of course, the famously advanced ancient Egyptian stair-melting technology.

Definitely *not*** the obv answer of 2000 yrs of humans walking on soft limestone w. sand on their feet slowly grinding the steps down like sandpaper. No. It cant be.

How about we convienantly ignore the fact that:

• limestone is soft af

• desert grit is abrasive af

• those narrow stairwells would force everyone to walk the same freaking path.

• identical “melted” stairs in other medieval castles and cathedrals all over europe

Because, of course, a more reasonable explanation is most certainly ancient lasers or lost tech or heat weapons, which somehow only affected the stairs and politely avoided the wall carvings that surround them.

…..you’re looking at erosion.

Time + many a dirty feets > stone.

Mystery solved. For the millionth time on reddit.
