I know for a fact that it does come from a star I just don't know how and why. Iv'e been trying to do some research on it but so far I had no luck.

Cal King say: The most abundant element in the universe is hydrogen. Heavier elements are synthesized inside stars. The gravity in a star forces hydrogen atoms to collide with each other and the products are Helium and energy. The process is nuclear fusion. The light we see from the sun comes from the energy produced by nuclear fusion. When hydrogen runs out, the Helium atoms will collide to form heavier elements. The process keeps on going until the star can no longer generate enough energy to keep its content. Depends on the mass of the star, the end of its life can result in the formation of a neutron star, a brown dwarf, a white dwarf or a red giant, or even a black hole. Our sun for example, will end its life as a red giant, and it will expand and engulf the earth. In some cases, the star will explode (called a supernova) and the heavy elements can be dispersed into outer space. New stars and solar systems can form and include some of the heavier elements. The earth's iron comes from the debris that was sent into space by an earlier star that exploded.

Brigalow Bloke say: Stellar cores are the only source of iron in the Universe, there was no atom heavier than beryllium for a few million years after the big bang.
See big bang nucleosynthesis and stellar nucleosynthesis.

spot a say: Yes
There is no other way for iron and indeed all elements except hydrogen and helium to have been formed. Elements up to and including iron can be formed in larger stars. When iron is formed in these stars it absorbs more energy than is required to make it and the star explodes in a supernova. Larger stars form heavier elements in a supernova explosion.
