Repeating what top space scientist has said. So an advanced race that can move across space from a planet outside our solar system, 4.2 light years away(5.8786E+12 miles x 4.2) and they crash on our planet. They are also advanced enough to make this trip but are so scared of us that they do not make contact. Then there is the lack of proof, with approximately 15 billion cellphones in the world that can capture everything in our life in clear color both as still pictures and video but there is not one clear undeniable picture or video ever presented. As for the conspiracies that governments are keeping things secret, that means that not one of the thousands of people in the government and outside contractors has not come forward with undeniable proof, just saying something is not proof, that all of the governments around the world are in cahoots to keep this information secret. Someone in the last 75 years would have needed or wanted to get rich by being the first to put this proof out and cash in.
