Is Bigfoot Living Inside The World's Largest Cave? | The Why Files & Cassie Coppersmith #bigfoot

The Basement: Cassie Coppersmith | Ancient Technology was More Advanced Than We Think Is Bigfoot hiding inside the largest cave in the world? On her third night in Vietnam's Son Doong cave, Cassie Coppersmith heard the safety guide give a strange warning: if you hear a baby crying in the middle of the night, don't worry about it. It wasn't the first odd thing. A porter sweeping a flashlight across the cave walls, explained away as "water buffalo." A side tunnel the guides refused to enter, with a different excuse every time. Bones on the floor of the Garden of Edam. Then clack, clack, on and on in the dark, and answers that kept changing: a squirrel, a bird, water dripping on a metal stool. Cassie explains why the baby crying sound is one of the most cited mimic behaviors in bigfoot lore, and why the dry part of that cave would make a perfect home. Then it gets darker. Her father-in-law's Vietnam War story, the kind of Vietnam rock ape encounter vets still talk about: a soldier grabbed by the foot, punched through his tent, nose flattened, medevaced and sent home with a Purple Heart, all blamed on "a big monkey." Is this the first Bigfoot Purple Heart? Her husband puts the odds at 3%. Cassie is at 75%.
