Suppose The Great Pyramid of Giza, also known as the Pyramid of Khufu or the Pyramid of Cheops, is the oldest and largest of the three pyramids in Giza, Egypt. It is estimated to have been built around 2560 BC during the Fourth Dynasty of the Old Kingdom. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years and is considered one of the Seven Wonders of the Ancient World.
Can we infer that "The Great Pyramid of Giza was built in the 20th century."? Yes, no, or maybe?
