Was an Ancient Civilization Discovered Beneath the Grand Canyon? “Kincaid is looking for silver deposits in the Grand Canyon. And he sees, like, this cave opening way up in the cliff. ... So he follows the steps and finds a way into this cave. ... He finds these porticos that have mummies on shelves, after shelves, just mummies. ... And he finds this giant cavern that is an old city that he says maybe people could have lived here.” “And then it kind of goes away. Smithsonian says, ‘We never heard of it. We never received anything.’ ... And the story disappears and so does Kincaid... People have gone up right above that hole to see what's up there. And once they go up there, as soon as you land above that cave entrance, suddenly black helicopters start flying around.” @OMGTheWhyFiles
