We will NEVER be visited by extra terrestrial life. The amount of luck required is too great. It's extremely unrealistic and foolish. 1) We need to come to the realization that it is and always will be impossible to travel at the speed of light or anywhere near the speed of light. Doing so would cause radiation particles, micro particles, space dust, and other little things floating around to hit the the crew and ship at extreme speeds and rip the ship apart. A bullet fired from a high powered rifle is only going 1,200 mph and can rip through metal. So imaging your space ship getting pummeled by particles at 670,616,629 mph and the faster you go the more particles you got bombarded with. There are no metals or materials that can sustain this type of damage because these radiation particles are SMALLER than x-ray particles so they'll pass through absolutely everything. And nothing can filter out or block this astronomical amount of radiation that will pummel the crew. We can wish and hope but it's a problem that is out of our control. 2) We need to stop falsely and foolishing assuming that there are aliens far out in the universe that can see us (2012) through a telescope. If you look at the earth right now (2012) from 65 million light years away, to the extra terrestrial, they are just now seeing light from 65 million years ago reach them. So to them there is no intelligent life on earth yet. It won't be another 65 million years until they are finally able to see us humans. By that time WE or THEY will be extinct. Because WE have the same problems THEY have. The vast majority of planets or uninhabitable and we can't travel fast enough to reach a planet, nor evolve or adapt to the bacteria on that planet fast enough to actually live on it. 3) We will most certainly never be able to "move homes" to another planet because the bacteria and organisms on it would be hostile to the point where we can't even safely evolve around it. We can live on Earth because for millions of years our ancesters have built up immunities to all the nasty viruses and plagues and flus that have come and gone. If an extra terrestrial landed here on earth they would not be able to interact with us in ANY way without wearing a bio-suit. They can't breathe our air or drink our water. And you think they're going to travel millions of years to get to a planet they can't even vacation on or enjoy or interact with in any way. 4) Extra terrestrial life that is more advanced than us has no reason to go on a suicide mission to come see us (a bunch of war-mongering primitive hairless baboons) To any potential aliens who are living millions of years away, we haven't even evolved yet. By the time they see us, we will be gone. By the time they travel millions of light years to finally reach us, both of our species will be dead. Us from extinction and them from getting blasted by radiation. Also, if they are more advanced than us why the hell would they want to come all this way to see us?! That would be like us traveling millions of years on a suicide mission to go see a planet of lemurs.
