The Ancient Egyptians changed from copper tools to bronze tools because bronze tools were better to work with then by 200 BC they changed from bronze tools to iron tools. With all these tools, the Ancient Egyptians created great monuments and palaces. It took them a lot longer than it would take the civilization today since we have better tools. They may not have been very high tech, but they knew what they were doing. They’re the ones who built the Great Pyramids, they’re still standing today.
