We’ve said it before, but as a reminder, 71% of earth space is comprised of ocean, yet 95% of it remains unexplored. Now, we are all familiar with unidentified flying objects, or UFOs. But, have you heard of unidentified submersed objects, or USOs? The first recorded USO sighting is from 329 BC, when Alexander the Great spotted a shiny shield like objects flying in and out of the river in India. He spent the next 6 years of his life hunting the object – and the hunt is what caused him to develop the first precursor to the submarine. Since then, there have been thousands of reports of USOs, but what are they? Could they be natural marine phenomena? Or are these advanced underwater vehicles developed by the United States or enemy governments? Are they underwater craft operated by extraterrestrial beings from other planets? And if they are being piloted by extraterrestrial beings, where are they going? Could there be advanced civilizations living beneath the Earth’s Oceans, like the lost city of Atlantis? Wouldn’t it make sense for a society to live underwater, if they had those biologic capabilities? And if so, could these civilizations know more about humans than we know about ourselves?
