what is youre oppinion?

Question

do you believe that allians,realy do excist has anyone ever seen anythng,to prove the fact,that there could be life on other planets,

Answer 1

That's a great question. Basically the answer to whether there is life in the universe is always a good one.

To answer your question, It's VERY likely that there other civilizations in this galaxy. The reasons is simple but you have to put up with some math and some history.

Back in the 60's some scientists asked the very same question, and came out with a basic formula that figures that out.

The main idea was fleshed out by a scientist named Frank Drake, he basically put some of the parts of the question together differently and assigned a likelyhood/probability to each.

Drake asked the question this way, what was the likelyhood of us communicating with another technically advanced civilization. Since that question breaks down, into parts that we can discover by looking around the universe, over time , we will be able to make a very good guestimate of how many civilizations are out there.

For instance one "factor" in his equasion was "the likelyhood of a sunlike star"

Another "factor" was "The likelyhood of a sunlike star with planets like Earth" - this gives you the basic idea.

The link here, takes you to a PBS special from some time ago which allows you to plug different numbers in and guess how many other civilizations there might be!

But this is where you can keep an eye on the headlines,

The French have recently launched a space-telescope which should be able to find "Earthlike" planets.

Corot Launched : http://news.bbc.co.uk/2/hi/science/nature/6203161.stm,
when "Corot" finds some planets, we can then do math to figure out how common they are ,and basically "know" one of the numbers Drake only could guess at in the 1960's.

In a few years the US/NASA will - funding allowed - be able to launch an satelite in 2008 called "Kepler" which will search for "Earthlike" finding space-telescope of our own.

Another question similar to yours is whether we will contact or ever be contacted by an alien civilization.

The SETI program in the 1990's and presently is designed to discovery signals from alien civilizations, and it is regularly if not constantly listening towards the stars for the faintest of signals.

But this question actually has a suprising answer, the answer may ALREADY be yes. The transmission is called the "Wow" signal and was detected on August 15,1977.

IF we asume the "Wow signal" is genuine, we would have been able to detect an alien civilization's message without it being specifically "for" us, which is a rare find, but after only 80 or 90 years could potentially mean the universe is crawling with life!

However, because it's just a fluke since we have not since found another "Wow" type signal,we shouldn't get too excited.

In the movie Contact (based on the Carl Sagan novel), the first 1/2 of the movie shows what a "first contact" situation might actually be like. It's unlikely that the signal would be able to be interpreted in the first couple of years or maybe even decades.

An open and interesting socioloigcal question is what would the immediate aftermath (on Earth) be of a first contact situation, the movie points out some of the "popular" disruptions to society.

Answer 2

I believe that aliens exist. I would be interested in finding a common langauge so as to communicate with them easily if and when I meet them. I would not be surprised if the communicative language were telephathy. I also believe there is life on other planets, partly for the wonderful mathematical explanation given by the soul above here on Yahoo! Answers, and partly just because I want to believe it. I believe the chances of it being true are very good. I have never experienced anything even remotely connected to any of this phenomena, but that doesn't stop me for a moment from believing in its possibility. I think it is because I believe in keeping doors open unless you have a reason to shut them.

Answer 3

Well, first you have to think about the questions you have asked.
1 Do aliens exist?
2 Has anyone ever seen them and have proof that life exists on other planets?


In answer to 1 - Yes, They exist without doubt. All you need to do is apply basic maths to it.
If Life developing on Earth was a Billion to 1 random chance. Take the numbers of stars THAT YOU CAN SEE in the night sky. There are millions of billions. If there are planets around, say, half of them (experts have found planets around all the Stars they have checked so far! This half is for the sceptics). That makes, say, a million billion stars with planets.
If life is a billion to 1 chance then it follows that statistically, Life will be on at least 1 million planets out there somewhere.

For 2? I don't believe that anyone has proof that Aliens have been here, BUT, they may well have visited covertly.
There are drawings and descriptions of strange shapes and lights in the skies from the Caveman era.
People may have seen something and attributed it to Aliens when it may be a natural occurence. Even the infamous Project Bluebook stated that there was about 5% of cases they investigated that could not be explained.
A civilisation that has the technology to cross millions of light-years of Space can easily avoid detection from a not-so advanced planet.

Answer 4

Ditto Danyelle

Answer 5

If you are an adult you should be an alien as normal humans dont spell as bad as you.
I think they do exist in some form or another. Maybe not as so called intelligent as us humans but maybe in the bacteria stage of evolution. Also if humans are intelligent why are we destroying our host (earth) surely paracites are the only other living organisms thats destroy their host. Intelligent I think not, Paracites, yes. 200 years from now our childrens childrens will look back in shame at their ancestors and say, "those are the people that destroyed this planet, we now have to live in it"

Answer 6

I understand there are more galaxies in the Evans than grains of sand on the earth so I think it's fair to assume
there are other forms of life out there

Answer 7

Yes. Aliens exist.

Just not around us.
The distances involved are too great, and I really dont think alies would come all this way to pick us up in the middle of the night, probe us, and put us back, when really, if they had any sense, they'd have given us a hand shake and said "Hi, we're here, nice to meet you all!"

Answer 8

of course they do....the sheer number of stars in the universe..possibly multiverse tells you that it's almost a mathematical impossibilty that there isn't life out there. Anyone one that believes that there is not life anywhere else probably also believes that god made the whole shebang in seven days....christ..if you can believe that then you can believe anything........including life elsewhwere.

Answer 9

Let's hope there is intelligent life out there because there isn't much down here on earth.

Answer 10

yes they do excist,my x wife is living prove
