Interesting article...

Technically earth comes from out of space...... so yes so does gold :P like our ocean is from a frozen comet that hit and melted :)
However gold came from the sun before our sun :)
A long long long time ago in our solar system there was a huge star.... this star was ending its life. (what this means is all the matter in the sun starts as 1 atom. "Hydrogen" after nuclear reactions happen to it it becomes 2 atoms "Helium" then 3 atoms and so on on until it reaches Iron, (all the mass of the sun pretty much has to do this so takes a very very very long time.... Once the sun reaches iron it becomes to heavy on it self and starts to collapse. When the sun collapses it turns supernova and goes boom! Now all the elements after iron are made in the 1-2 seconds big boom in the supernova where it has enough nuclear power to fuse atoms together...... (eg gold and silver)

After this big boom there is a little star left where the big one use to be :) know known as our sun :) All the stuff that got blown up in the supernova blast started joining together with gravity and over a long time became the planets in our solar system we see today :) Iron and other heavy elements sunk to the core of the planet and slowly gets pushed back out with the other elements and that's where gold comes from :)

However there is also meteorites that also bring gold and other elements that land on earth..... these would be chunks of the early big star or from anther star a long long long way away that has done the same supernova boom. As all elements above iron on the periodic table are formed in that 1-2 seconds when a sun goes supernova.

I could also go into how the moon was once our twin planet and lost a duel with us ....... now there core helps create our magnetic core :) and whats left of the twin planet is now our moon slowly floating away after hitting earth before the crust was even formed. That twin planet covered the early crust of the earth with heaps of elements such as gold and iron... which a lot of it sank into our core making our planet larger.

Some people may have other ideas but this is what i have learned :)
