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.  |
It's actually worse than that. Your 4.2 light years would be the closest star to Earth, Alpha Centauri, which has no confirmed habitable planets. So it's likely that any travelers would be coming from much farther away. Add to that the need to travel much faster than the speed of light, which is currently believed to be impossible, and the issues with space/time at those speeds, and visitation becomes even less likely.
If you do a little google searching, you'll see that after WW2, many believed that some Nazis escaped to the moon. This was because after the war we discovered their work on rockets, and people knew very little about the complexity of space travel, or about the habitability of the moon. Once the public knowledge of both grew, those beliefs quickly dissipated.
I put UFO's in the same category. If people really understood the complexity of FTL travel, and the vast distances of space, most would understand that it is highly unlikely, even an impossibility that we have ever been visited.
That does not mean their isn't life on other planets. I just believe that it is rare, and far enough away that we will never know on this side of eternity if it exists.
