Dogs. Who knows what goes on in their dog-minds! But...the Pyramids are nothing to sneeze at.
When I was in the Navy, we made a port call to Alexandria, Egypt, and they had tours out to the Pyramids.
This was back in a time when you were allowed to climb on them, and many sailors did. The blocks at the bottom were larger, IIRC you had to hoist yourself up on the first few, but after that, you could kind of climb them.
The problem was, as you went further up, the stones became progressively rounded and crumbly, with grit and sand on them.
I got a few levels up, and in a flash of realization, understood that if I slipped, I was going to go all the way down the side of that pyramid and get killed, if not badly hurt. I gingerly climbed down, and that was that.
I have heard that a tourist was killed in just this fashion some years ago, and they banned climbing it after that on the basis that they were precious antiquities.
That’s not pharaoh.
