Hell might as well ask why they needed to come down to a planet to mine anything.

Gold, among many other minerals and metals are located in the asteroids of the asteroid belt.

Far easier to collect asteroids, bring the material on board a ship and then use solar power to smelt the ores you get then dump the slag back into space, or send it on a trajectory that ends in the sun... or around a planet that could use a large moon say like Mars.

The fact that the asteroid belt exists strongly suggests that no mineral starved aliens have been around here. If the would have arrived long ago the asteroids would no longer be there. Many are rich in nickle and iron, and containing high levels of iridium and other rare metals not found on Earth.

For a space based race, all of these metals would be dear to them, thus they would not just mine Gold, they would mine everything most likely including the slag which itself could contain chemicals that they could easily extract and utilize.

If they were looking for water, they would not need to come any closer than the Kuiper Belt which is rich in water ice and organic compounds. Thus if a thirsty space race visited our solar system we would not have comets today.

We have already mined out many of the surface metals and minerals, we have to dig deep - real deep. Ever see the Salt Lake copper mine? There are a few dozen super large open pit mines in the world. If we were to abandon them they would still stick out like a sore thumb 10 thousand years down the road as a geological anomaly. If a gold starved species came here they would not be satisfied with simple primitive tunneling, they would go big and dig out huge pits leaving huge holes that would stick out and be well known to us today.

This 'facts' rarely get any attention from those who insist we were created to be a labor force.

However if you consider how we operate mentally (everything is sex or is in the attainment of sex) then we should conclude that we were bred to be sex slave, pleasure givers to our creators.

That makes a bit more sense and may have more of a scientific leg to stand upon than 'mining gold' does.


I know.

The fact that gold is more plentiful in space than on this measly little planet is a fact that I didn't touch upon.

Personally, I don't believe that we were created to mine gold for aliens, because of all the improbabilities involved with it.

Two of these prominent improbabilities are the facts that A) gold can be found in great abundance in places besides Earth and B) The time and effort involved in creating a slave race to mine ores for you seems highly inefficient when much better avenues exist, such as robots or other technologies.

I was just posing the question to those that do believe in this.
