The American movie titled "The UFO Movie They Don't Want You To See.", explains the truth about e.t. life. They even explain the nimitz, tic-tac, and gimble videos which even the u.s. pilots thought were aliens. Now we know that even the videos released by the u.s. navy are fake. I was so believing in that one b/c I thought "hey, it's the u.s. navy...." But they were wrong wrong wrong. Even the Jimmy Carter UFO is explained in this movie.
Meanwhile SETI is still searching for a signal and the only signal SETI ever got was in the 1970's called the WOW signal. It was a radio signal at 1.42 GHZ. (They explain the reason that all e.t. life would use this frequency.) SETI hoped that the signal would carry some sort of information encoded in it, but either it doesn't, or no one has been able to decipher it yet or figure out how the information is encoded. But do keep in mind that the distances are so great between solar systems in just our own galaxy, that even though there are over 60billion planets in our milkyway, it would take thousands of years to reach them on a spaceship, so unless aliens live forever they are not travelling space. You see nothing known to us can travel faster than the speed of light. Einstein was a lot smarter than you and me, and according to many real scientists who understand the Einstein temporal equations, He's right. This is why most of the people on earth who claim there are ufo's taking off and landing every five minutes are just outright lying to you. It's not happening. We wish it was. But the simple truth is SETI also has equipment which would know if there were aliens taking off and landing, and it just is not happening. But people are stupid, they will believe whatever anyone tells them or swears to... Will you?
