We aren't just finding out about them but they're still not verified. My verification came when Elon wanted to have an underground system using air to push pods that would travel coast to coast in a short time. I couldn't see them digging a tunnel from NY to LA with his track record in business at the time. Money and he tends to do business in things that have been invented and supressed. I guessed the tunnels existed at that point and I'm waiting to see. The earthquakes, tunnel rumors and music videos and movie with children in dreary places makes me feel it's real.
