According to legend it was tubalcain who first made use of meteorite iron:
Even if ancient people never seen a meteorite land near them they would have seen shooting stars and would have known objects fall from above. I'm sure they would have sent search party's out to see what the object was. When they would come across a rock buried in the middle of a crater they would have known it came from above.

...and explains that all of our planet's gold, silver, and platinum may be extraterrestrial in origin.
I believe you may be interpreting that statement in ways it wasn't intended.
Ultimately, EVERYTHING on Earth (and Earth itself) is "extraterrestrial in origin." The atoms were forged in the hearts of billions of ancient stars which turned hydrogen into iron and other elements. Supernovas distributed the atoms across space, and gravity formed and reformed stars and planets.
But the gold that's found on Earth is strictly from terrestrial sources. Meteoric iron does exist, but it's in very small amounts.

The latest isotope study showed that metals were present during the Earths formation 4.5 billion ya however most of the terrestrial "precious metals" are buried too deep for us to access.
Most of the precious metals we access were deposited during the meteorite "terminal bombardment" which apparently happened 3.9 billion years ago meaning that most gold mined to date is extraterrestrial in origin.

In 1911, archaeologists dug up strings of iron beads at the Gerzeh cemetery, about 43 miles south of Cairo. The Gerzeh bead is the earliest discovered use of iron by the Egyptians, dating back from 3350 to 3600 BC. The bead was originally thought to be from a meteorite based on its composition of nickel-rich iron, but scientists challenged this theory back in the 1980s. However, the latest research places this theory back on top. The scientists used a combination of electron microscope and X-ray CT scanner analyses to demonstrate that the nickel-rich chemical composition of the bead confirms its meteorite origins. Philip Withers, a professor of materials science at University of Manchester, said meteorites have a unique microstructural and chemical fingerprint because they cooled incredibly slowly as they traveled through space. He said it was interesting to find that fingerprint in the Gerzeh bead.
