No. the element iron requires the heat and pressure of a sun like ours to be able to form iron atoms. But our Sun did not produce the iron we have. The iron we have on Earth was made in a larger star that went nova.
This iron was amongst the debris field from which coalesced the Earth.
In early times, when oxygen levels were quite low, it is believed that much of the iron would have been dissolved in the oceans and they would have been rather green. After the algae invented photosynthesis, this increased the O2 content of the atmosphere, and the iron was precipitated out as the Banded Iron Deposits, which form much of the important iron deposits worked today.

Why do geologist think earths core contains mostly iron?
Other orbiting bodies contain more iron then earths crust does
Why do scientist think earth's core contains iron?
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
Why do scientist think earths core contains iron?

Earths crust is mostly made of what iron oxygen or silicon?
Earth's crust is mostly made up of Silicon and Oxygen
Is the earths crust less than one percent of earths mass?
With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.
What is the earths under crust surrounded by?
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.

Where can iron be found?
Iron can be found in Earths Crust
What is the iron percentage in the earths crust?
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.

Why is the iron catastrophe called a catastrophe?
the earths iron catastrophe was when earth got hit by a metor the size of mars and all the iron on the mantle melted in the lava and formed the earths core(inside).
