Yeah if nothing else makes you think doesn't it!If you look close you will find it's been possible to make tiny, tiny amounts of gold with hi-tech hard to find super expensive machines and hi-tech manipulations. It costs a fortune just to make very small amounts less than an ounce.But its doable.
That alone should make us think if we have technology from crashed spacecraft and have been trying to figure out how they did what they did for decades,its likely we figured out how to do a lot of things.Is making gold one of them?Hard to say.
