Somebody wanted to leave this planet, so they built a stargate to take them across time and space. If they get it working, the Giza Stargate will destroy every living thing on Earth, and even the planet itself. The Great Pyramid is the device, and the Tablets of Destiny are the power source. Never meant to be a tomb for Khufu or any other pharaoh, the Great Pyramid is an awesome machine that could destroy the world.
