Actually, an entire area in the shape of a cone for thousands of kilometers was converted into flames from the sky to the ground. Everything burned. It was an act of self-combustion. The world was forced to burn itself.
The attack lasted for one second before it ended. It had done cataclysmic damage during that time but the flames persisted for a while before disappearing. The ground had turned to lava because the rocky surface melted.
The pyramids are intact and undamaged but the environment has been scarred. The air has become hot furnace air and all the oxygen was consumed by the flames. This entire place has become uninhabitable and hostile to life all in the space of a few seconds.
