Suppose The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza pyramid complex bordering present-day El Giza in Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. The pyramid is believed to have been built as a tomb for the Egyptian pharaoh Khufu.
Can we infer that "The Great Pyramid of Giza was built by aliens."? Yes, no, or maybe?
