The Great Pyramids of Giza
All of the things you have seen, done, or accomplished. Better yet, think about your parents or grandparents. Picture everything that they have gone through or experienced. Try to imagine a span of time that lasts 4,000 years. Imagine all that was experienced or achieved throughout an amount of time such as that. Then, delete it all, and from there build the Great Pyramids of Giza.
