Iron is made inside stars , specifically red super-giants. The elements form together inside a star during fusion. When the supernova occurs, the iron fragments are blasted into the space. This is how Iron came to Earth millions of years ago.
Where did iron come from?
Iron makes up about 5% of the Earth’s crust and a large part of the Earth’s core . Iron also comes from meteorites. On earth Iron is found mainly inside the minerals hematite (Fe 2 O 3 ) and magnetite (Fe 3 O 4 .) Removing the iron from these minerals is a reasonably long process involving many large industrial factories.
Where was iron first discovered?
Archeologists believe that iron was discovered by the Hittites of ancient Egypt somewhere between 5000 and 3000 BCE. During this time, they hammered or pounded the metal to create tools and weapons. They found and extracted it from meteorites and used the ore to make spearheads, tools and other trinkets.

Can iron be created on Earth?
The only elements that were formed on Earth are those produced by radioactive decay . There are four natural decay chains that start with transuranic elements and none terminate in iron; neither do the decay chains that are artificial or those that result from cosmic radiation.
Is iron native to Earth?
Iron, nickel and cobalt
Most of the native iron on earth is actually not in fact “native” , in the traditional sense, to Earth. It mainly comes from iron-nickel meteorites that formed millions of years ago but were preserved from chemical attack by the vacuum of space, and fell to the earth a relatively short time ago.
