No aliens are actually known to exist. No hard proof at all, just stories.
-----------------------------------------------------
Space aliens do not exist. The human race is alone in the universe.
------------------------------------------
Space aliens may have already made contact with us, there is no way to know for certain that they have not. The chances are good that they haven't, since they can travel through space, and that seems to indicate an advanced society. Therefore, an advanced society might not want to contact us at our stage of development. We after all, are a fairly worrisome group when we need to be. They might be waiting for us to reach a level of intelligence greater than we are now, so we would have a better understanding of their technology. Maybe they would want to wait for us to obtain some unknown level of social understanding, so we could adapt to their society easier. It may be a matter of simply, we are not who they were seeking, or we are, and they came only to watch. There are many reasons that a far advanced race, capable of traveling the stars might not contact humans, each stranger than the first. But don't forget that they might be your next door neighbors, and would we really know. If they are truly space aliens, then we have no way of guessing, and we might be talking to them now.
--------------------------------------------
We don't know for sure there are any aliens *to* contact us. No hard evidence at all, not even one strand of alien DNA. So far, it's all just stories, myths, tall tales. And no matter how high you stack those, they never become evidence.
-----------------------------------------
Some claim that aliens are a classified subject insofar as the government is concerned. To date, no one has turned up any proof of this.
-----------------------------------------------------
Steven Hawking said the following "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational,". "The real challenge is to work out what aliens might actually be like." Hawking believes that contact with such a species could be devastating for humanity. "We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet." "If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans." "I suspect there could be life and intelligence out there in forms we can't conceive," he said. "Just as a chimpanzee can't understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains."
---------------------------------------------
The universe is large, which makes other life seem likely. But likely is not proven. Someone has to be the first form of sentient life, and there is no actual proof it isn't us.
---------------------------------------------
There is as much evidence that unicorns exist, as there is that aliens do. Bear in mind that anecdotes are not evidence, no matter how many anecdotes you stack up. Since no aliens are known and proven to exist, there is no point in worrying about their failure to contact us.
It's a big universe, but someone somewhere has to be the first form of sentient life, and there is no proof it isn't us.
they dont they are just plastic aliens but u can make babies with them
to make sure aliens dont come down to earth and suck out yo brains. they can also tkae yo temp.
Sorry to disapoint you but i dont think you can... =(
i dont no
They made lasers to defend the world from space aliens!!!
no they dont its only the people do it to scare us
They were the first civilization to make contact with aliens
no. dont make contact with him. guys need their own time and space to work things out properly. if you contact him, he is likely to get aggitated and annoyed with you. if your a friend of his, the best thing you can do for him is let him know that you're there to support him. if your his girlfriend.. do the same thing. dont badger him.
Probes are used to get samples and to also see what there is on other planets
well i dont think it works but DONT put it in the freezer if it works it kills them
simply make a serious sexy eye contact with them.
A close encounter of the third kind is when we (people) actually make contact with Aliens .
