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.

Yes I do and I think there are quite a few different species even in our own area of the galaxy. I think the aliens could be based on other elements instead of carbon (such as ourselves) as well, as it has been reported some aliens appear as a gaseous form, and than some have been reported in other physical types of appearance also. There is no doubt in my mind they exist, but I am mainly concerned with is what their plans are for us "humans" already here on Earth right now are and into the future !

YES! the fact that we still havn't found one, doesnt mean there couldn't be any. to answer this question, we have to refer back to science...
how did science explain, the various lifeforms on earth come about? EVOLUTION. even if you do not believe we evolved from monkeys (i don't), many lifeforms have gone through different changes. that includes amphibians, reptiles, mammals, bacteria, viruses, etc2. and some of those changes are visible today. like how chickens have grown smaller (other than because of genetic modification) and epidemics getting stronger... as science explains, it all started when the conditions/environment was hospitable for life to exist, small organisms start to appear. then the whole process starts...
if it can happen on Earth, why not elswhere? the laws of science allow life to take place. besides, scientists have proven that there could have been life on Mars (though they think they could have killed em decades back).
and yes, they could come in all shapes and sizes. the universe is so large, who knows, there are aliens the size of Earth =P
(but that does not mean they are as technologically advanced as us. as far as we know, there could be other cavemen lifeforms out there thinking, "do aliens exist?". hey, we could be aliens to them!)
yup, science cannot explain everything (men with magnetic bodies, telekinesis, etc...). if science itself can explain life, what more the extraordinary/unexplained? ;)
hope this helps.

NO DOUBT ABOUT IT i do believe in extraterrestrials 200% percent. I'm not a weirdo i just do believe in the fact there is a great Chance other intelligent life is out there and has visited us. I just wonder when will they reveal themselves or is there a huge conspiracy going on that has the entire planet on the ( Dumb people; don't need to know anything; continue your lives with no interference). Why would you say you don't believe in aliens if hundreds of thousands of people believe in them and 70 % of them seen a ufo , 20% of them have actually seen them land , and 10 % have been abducted and have lived to tell the story but we say that they are insane i just have to say those who don't believe in possibility are ignorant and those who believe know what I'm talking about.

I believe in aliens and aliens believe in us.
They know we exist and they also know that they will never meet us though I am sure they would like to.
