That's non-controversial, regular knowledge right? That the proto iron age happened all over in 1 or 2 centuries in which meteors dropped iron from the sky. It was in regular history books when i was a kid.
They always brush right over why it was raining iron. Isn't that crazy wth is that about?
It is true there is a lot of iron. 10% of total mass of 26 and above is generally accepted. Also true Iron and higher mass numbers are created in stars of predictable mass. This is not true with lower mass elements. In fact 1 thru 25 can be and are produced in various quantities even inside earth. While Fe accounts for 10% of mass of all higher elements, don't lose sight of the fact it is far from the most prevalent. H accounts for 90% of the known universe, 2 thru 118 for the rest. "But it can also be a liquid yet stable form" True but a miss use of terms. "Stable" simplify means "not radioactive" ... it's not in the possess of becoming a different element. Also, the crust, a tiny portion of the earth, is mostly solid rock. The majority of mass is in the mantel and is "plastic state" with many LLVSP's very out of balance protrusions... not at all nice little symmetrical shells of concentric nested balls like the nice picks from grade school. Does it make a difference? Yea, it does. I don't know your age but you may well live to see why.
