Evidence from ancient civilizations have depicted what some say are firsthand introductions to off-world life forms. These days in our highest tech world all we get are a few lights and a blur on a video of a "recon" mission. Perhaps they were once unafraid of us in the arrows and slings days but today things are different. Hollywood usually depicts a human victory over unfriendly aliens in the form of a nuclear or biological event (except Slim Whitman). In the Forties, two things happened, we used nuclear weapons to stop the last of our world wars amongst ourselves and Roswell. Was the cold war an actual sharing and distribution of technology to ensure a global nuclear defense against a recently confirmed potential off-world invader? Are test firings an ongoing warning to BTFO?
