Silver is bi....not that there's anything wrong with that.

can you hear the hammering of the pulsar ?

Yes it does and it does genuinely exist on earth.
In fact the first iron tools where made from iron meteors, as mining had not yet developed.

I mean the source of this Iron is from meteors , isn't it ?
Iron is formed in massive stars which then go supernova. The debris, including
meteors, eventually forms planets. So I'd say iron comes from Earth & meteors.

I strongly believe that Iron came from meteors only.
because Iron needs tremendous energy to be fromed, and that tremendous energy does not exist in our solar system.
then It must be came from outside our solor system through meteors .

The core of this planet is iron..there are not enough meteors...nor any way of accounting how meteor iron ended up in the core.
We couldn't have a supernova in our solar system & survive it. That happens before the solar system is formed.
Iron gas & small particles could also condense into a planet....but I don't know....I wasn't there.

Indeed our sun accreted matter from earlier supernova...into planets and whatnot..as it moved into the nebulae/molecular cloud that preceded our solar system.

what about Iron mines ?, can scientists figure out whether Iron came from meteors or it is genuinely exsist in earth when it was first formed.
There's a question which is above my pay grade. But it appears that most of the mass of
the Earth is from elements not produced in our Sun, so where did the Earth come from?

Considering there's a block of iron weighing 1.1 trillion billion tonnes at the centre of the planet, I think most of it was there originally.

I think so too..at the very core though I suspect that there are large quantities of heavy radioactive elements.
Which may in part or wholly explain how the outer core remains liquid for billions of years...(releasing heat energy as they decay)..and of course the resulting tectonic activity of the crust, pushed around as it is by the conductively heated mantle....and perhaps the true origin of the majority of radon gas.
Just a thought...my earth sciences knowledge is infantile really.
