We know the Anunnaki have mined and removed massive quantities of gold from the Earth. Have they done the same with other minerals? Other channelers have depicted Earth as a valuable DNA repository. And most recently, it was suggested that chocolate is one of the most valuable and sought-after commodities that Earth possesses. Is this true, and is there anything else Earth-based the interstellar market considers valuable (besides human slaves)?

Because your world has been subjugated for so long, humans have little to offer other than their own flesh as meat to other worlds. The Earth itself has been plundered already of minerals that are of value to the Extraterrestrial Alliance membership, primarily gold which has practical utility for preservation of their planet in providing an energetic shield of vast size, but also, because of its innate physical characteristics, is considered valuable in many civilizations and they have retained that perspective and have sought to hoard it for that reason. There are many, many worlds that are mineral-rich but it is far easier to obtain those riches without native species that could be capable of mounting a reprisal for the extraterrestrial intrusion. So anything of real value has been removed from the Earth already millions of years ago. The idea of chocolate being a particular prize is a kind of human conceit and perspective that is not shared. Humans have a very limited ability to appreciate the potential for enjoyment of things, on a physical level even, because of the subjugation of their world. Anything that an extraterrestrial species might appreciate and enjoy has been taken and cultivated and spread widely long, long ago, so the human race will never be in a position of commanding a marketable commodity of interest to other worlds.
