Here’s where it gets hilarious. How do you drag a 2.5-ton rock across desert sand? You pour water on it. Seriously.
Wet sand makes the ground hard and slippery. It reduces friction by a crazy amount. A team of maybe 20 guys could pull a block on a wooden sled. No wheels. No magic. Just really soggy ground.

A recent experiment proved a sled could move a huge block with just a few men if the sand was wet enough. Ancient Egyptians were basically the original bad-A engineers of friction.
