Tens of thousands of years ago man lived only for survival. They may have traded for things they needed but were probably mostly on their own. In the last 5000 years or so before any bibles were written people have been searching for gold. Most people today don't believe in alien interaction with (humans ?). If there were none, what do you think inspired them and the knowledge of where to find and mine gold? It takes a lot of resources and effort to mine gold when you could be spending the time and energy to do things that needed to be done just for basic survival. It's not like they needed gold for technology or electronics. They must have known that gold was a significant resource or else why would they bother..... any thoughts......

Gold has certain values for us on earth, and obvious values for electronics and other high tech uses on earth. Why would you assume it has any value on other planets, or even if it did, assume it is a rare element on other planets at all. It could be totally useless other places, or have such abundance it, has no value at all. Aside the technical uses of gold that at best has evolved in a short time in history(electronics, Space, etc) its value was rarity for vanity uses, burial, religious artifacts, etc.
Why it would ever be cost effective to mine gold even from the moon(not sure it is there), would be ridiculous. Just going to Mars a year journey, why would we care to make the mission about mining gold? And be able to return it to the earth, nobody could afford it or what it would be used for. Why any life form would or could come light years to visit us, would not be for gold.
Bottom line the most valuable thing to us might be totally useless to other worlds. Our standards in our culture values it, others may see it as a primitive use for something worthless. If you had all the gold on earth, and not one glass of water, what good is it.
