Scientists believe iron was first discovered in Egypt. Iron has been found in many ruins across the ages, ranging from as far apart as Mesopotamia and the western Roman Empire, but the oldest iron relics were found in Egypt and date from around the year 5000 BC.
Scientists believe that the first iron worked by humans fell from the sky in the form of a meteorite. This is because iron tends to be found far beneath the surface, making the presence of iron uncommon until proper mining techniques were developed.
Most meteorites are made from stone or rock, but a small proportion are almost entirely iron, and they are known as iron meteorites.
Though iron artifacts have been found from around 7000 years ago, they are extremely rare because iron corrodes much faster than silver or gold, meaning the vast majority of iron relics are destroyed before they can ever be discovered.
