The Miracle Of Iron !!

[downbeatplumb]

Yes, that sounds right. This is why the moon has no iron and we have lots! The moon is therefore an extension of the Earth's crust.

But of course this is all part of the formation of the Earth and you cannot use this example as iron being sent to the Earth as before this impact the 'Earth' was basically a different planet. In a way you could say that Theia and whatever you want to call the planet that was here before are the parents of the Earth.

Anyway, the Qu'ran saying that iron was 'sent down' to the Earth is simply a classic example of assumptions made based on the knowledge of the time. i.e. you see rocks made of iron fall from the sky and you assume that this is how all the iron got here. And if you are prone to belief in magical deities then you further assume that he sent them down as a gift for you.

You are of course correct.

I was just pointing out that a significant amount of iron was not due to accretion.

In fact, due this added influx of iron earth has a higher density and larger magneto sphere than you would normally expect for a planet its size with important implications for life.
