How Did the Pyramids of Egypt Stay Standing for Thousands of Years?

The pyramids stayed standing because they were built with very strong stones and a smart shape. When you stack blocks in a pyramid shape, it makes the whole structure more stable, like how a tower of blocks is harder to knock over if it’s wider at the bottom. Also, the stones used were really heavy and smooth, so they fit together tightly without needing glue.
