I have been following UFO history for about 10 years. Bottom line is, when you do the research and look at the evidence with an open and unbiased mind, you find 98% of it is nothing. But that remaining 2% of strong evidence is quite remarkable. That 2% made me a believer 100% that we are being visited and have been visited for a very long time. It was just 100 years ago humans invented the automobile and airplane, where now we have multiple probes scanning multiple moons in our solar system. It's not all that hard to comprehend that an advanced civilization, or multiple civilizations, that have had advanced technology for thousands of years, can travel via dimensions or bend space and time, or even send probes to earth. There are billions of stars in our galaxy alone that spans 100,000 light years across. There are billions of galaxy's in the universe. Being visited is not just possible, it's probable.
