No one "made" gold here, they refined it from an ore. The only difference being they used bacteria to refine it rather than an industrial process. The only way to make gold is with a supernova.

Slow it down, maybe. But the amount of earth's resources required to launch and operate spacecraft takes a terrible toll on our environment!
That's why asteroid-based mining + 3-D printing is the way to go.http://gizmodo.com/how-asteroid-mining-could-pay-for-our-first-space-colon-1685429089
