do aliens exist?

Answer 1

Only until they get their Green Card.

Answer 2

Our Milkyway galaxy has some 400 billion stars and many are the same as the Sun or similar.

Given that there are as many, if not more galaxies in the known Universe as there are stars in our Milkyway, each with between 100 and 500 billion stars; a great number of those stars are going to have solar systems and a great number of them are going to have planets with conditions that can support life.

Currently we are aware of 119 extra solar planets and as our technology uncovers more and more, it is a racing certainty that the Universe is teaming with life. Personally I believe that life is the DEFAULT condition of matter!

However, because of the tyranny of distance it is perfectly feasable that we will never meet these extra solar civilisations because they can't get here and we can't get there. Also any technology that they might display would be unreadable, even within the next 500 years.

At light speed of 186,262 miles per second (7 times around the World in a second) it would take slightly less than 2.5 Million years to reach the NEAREST galaxy which is a greater expanse of time than the total existance of the Human species on this planet. A round trip would take 5 Million years and that includes all known forms of radio and other electromagnetic radiation.

To reach the furthest galaxies and stars at light speed would take upwards of 18 billion years, more than 4 times longer than the Earth, Sun or Solar system has existed.

My point is, just because we don't and can't see them doesn't mean that they are not there. As far as I'm concerned the Universe is positively awash with life but we may never meet them or know of their existance because, quite simply they are so far away and they will never know of us for the same reason.

Do Aliens exist?, Absolutly they do!, in their myriads.

Answer 3

If you study Astrobiology, and in particular the extremely rare combination of circumstances that brought about the opportunity for multicellular, and eventually our species to evolve over millions of years( a highly metalliferous sun, a large moon, plate tectonics and a carbonate cycle, a location well away from the galactic core and in an optimum and nearly circular Goldilocks orbit [not too hot, not too cold], and a rift valley like that in West Africa where Homo Sapiens evolved, which resulted in several different types of environments fairly close together), you may well conclude that it is highly unlikely at this time in this galaxy of more than 100 billion suns. Even in a universe of 100 billion galaxies (many unlike ours), I would expect life to be fairly common; multicellular life much, much less so; animal life even less. Intelligent life forms; even rarer, particularly those which have developed technology ( look at ancient Greece and Rome ), and those with not only the capability, but also the motivation to use that technology to communicate or travel interstellar distances would be very few indeed. SETI (the search for extraterrestrial intelligence) has been going on for decades now with no results. Try Googling SETI and Astrobiology.

Answer 4

We exist. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

Answer 5

I would say chances are very high that there are other life forms in the universe. It would be selfish and egotistical for us to think we could possibly be the only life forms ever created and that our planet is the only one that could ever spawn life. There are tons of planets out there that have their own sun(s) and are like ours. The chances of life being on at least one of them, I believe is very likely. Anyone who would say no are very close minded.

Answer 6

I think so but then again i also believe in extraterrestrial humans as much as extraterrestrial alien life, maybe that's why i don't get dates these days.

Answer 7

Although we will never meet one or even prove they exist it is a certainty that many of them are out there and asking each other the same question about us!

Answer 8

yes i do believe they exist
most people that say they have had an encounter seem to me to be a bit dubious.
the solar system is a big place for starters.
then theres the universe,think about it

Answer 9

of course they do not on this planet but they are out there there are billions of planets in the universe all made up of the same stuff as earth

Answer 10

Maybe
