The pyramids were built over a period of several centuries, with the first pyramid being constructed around 2650 BC. The Egyptians used simple yet effective tools, such as copper chisels and wooden mallets, to construct these massive structures. It's estimated that it took around 20 years to build the Great Pyramid of Giza, with a workforce of around 100,000 laborers!
One of the most interesting things about the pyramids is the way they were built. The Egyptians used a system of ramps and pulleys to move the massive stone blocks into place. They also used a technique called analogous construction, where they built a smaller version of the pyramid first, and then used that as a guide to build the larger structure.
The pyramids were also believed to have spiritual significance, and were often built as tombs for the pharaohs. The Great Pyramid of Giza, for example, is believed to have been built as a tomb for the pharaoh Khufu. The Egyptians believed that the pyramids would provide a safe passage for the pharaohs into the afterlife, and would protect them from harm and danger.
