Whatever you think of mankind, and the unlikeliness that we are alone in a universe filled with billions of stars, take a gander at this recent upload from one of my friends. While attending the UFO Congress in Arizona, I learned a great deal about the alien agenda and the cover-ups from governments around the world. Are we alone, is it possible that Earth is the only planet which lies in the The habitable zone, sometimes referred to as the “Goldilocks Zone” a region around a star that has just the right conditions to find liquid water on a planet’s surface. And liquid water is a key ingredient in the search for life.
