Brian believes in time travel and the unbelievable and somewhat ridiculous and impossible to prove multidimensional String Theory,... Yet depsite the relative ease in which life has developed on Earth, combined with the trillions of exoplanets in the universe, Brian cannot conceive we are already being visited by aliens. <br>How much extraordinary evidence is necessary, to convince our frightened little scientists that we are not alone?<br> The evidence is right there if they choose to look, even if we ignore all of the hundreds of ufo sightings by trained military pilots and personnel and the fact that our government's have spent millions studying ufo for decades,, <br>(and have collected evidence so compelling they have classified it higher than the president) there are countless ancient religions with stories of beings from other worlds, along with  ancient buildings that defy all logical methods of construction for their time period, plus drawings, carvings and cave paintings, depicting aliens. <br><br>In less than 50 years, as has happened so many times in the history of science,  it's highly likely many of Einstein's theories will be superseded by the next Copernicus or Gallilleo and faster than light travel will be proved possible or circumvented to allow instantaneous transportation. <br><br><br>If you believe in evolution, you'd have to be really daft not to believe there has to be life on other worlds...<br><br>And why don't the aliens say hello? Because they'd have to be daft to do so,  they'd be captured and their technology taken before they could say live long and prosper! <br><br>Look at the terrible way we are still treating this planet and our fellow human beings,,  our prisons are full and still we have millions of crimes, rapes and murders every year,  wars and military conflicts abound, indigenous  people continue to be driven from their land in South America and millions of acres of Rainforests are destroyed every year in the name of greed. We are a very primitive species at best. Just think of the havoc we would cause if we had the ability to travel to other Earthlike planets! The movie Avatar says it all.,(reply>), we would like evidence of actual aliens.<br>and not "look how amazing trees are" argument<br>and "we dont know therefore aliens"<br><br>UFO doesnt mean aliens.<br>eyewitness testimony is worse type of evidence you can find.<br><br>if you think that aliens if they came to earth to say hello, and that we would be able to capture them and take their technology you are deluded.<br>like you come to north sentinel island with an battlecruiser and aircraft carrier to say hello to people in stone age.<br>you think they could capture you and take your technology?<br>with what? arrows that cannot even reach the stealth bomber.<br>you could maybe capture one alien.<br>depending on its physiology, maybe it would evaporate you with its acidic venom sack from its mouth<br><br>avatar is a movie.<br>that is your problem.<br><br>better watch predator. that is more like how it would be.<br>humans hunted for sport and nothing else.<br>they dont even deserve to communicate with.
