There are some who must have facts in black and white in order to accept anything as true. There are others who simply believe on blind faith.
As far as believing in the existence of intelligent life on other planets, I can only quote the line from the movie "Contact" when the question of the possibility extraterrestrial life was asked: if we are the only one's in the universe, it would be an awful waste of space.
Learn about the Drake Equation and then decide for yourself! And don't be afraid to use numbers just slightly larger than most people use for it.

Firstly there are as many stars as there are grains of sand on every beach in the world (Carl Sagan). So, if most stars have planets, then your guess is wildly out to the tune of several quintrillion.
From a scientific viewpoint, you can only be definite about extra-terrestrial life if you have either detected it, or you have a mechanism by which life would always develop from inanimate matter.
At present, neither option presents to us.
In reference to other answers here:
Firstly it is incorrect to say that mathemtaics proves the existance of alien life. Mathematics only shows us that there must be billions of planets that have the conditions for life. You have to factor into that the likelihood of life spawning from inanimate matter - that is a complete unknown.
Another repsondant mentioned the old Drake formula, even though he couldn't remember the name. Scientists have since brought many other factors into the equation that make our planet Earth and the Solar System so unique that it is mathematically feasible that intelligent life only ever developed here.
And NJGuy below quotes the saying from "Contact". The fact is nature is wasteful, in a sense. Even in our own Solar System, only one 2 billionth of the sun's energy hits the Earth. The remainder goes off into space. All that solar Energy and we only use a 2 billionth - like building a nuclear power station to keep one bacterium warm.
It may be that the whole of the universe exists so that there was enough matter for pure chance to come along and create the most complex molecule in the universe - DNA.

Well, there is definitely something going on.I have had some personal experiences that have left me even more confused about who is playing god with us. Whether raptures are actually abductions etc. Someone is here and possibly even been here before us.I'm fairly certain we will know something very shortly the way this world is headed.Enjoy as much of your life in an honorable way for now and expect something major in the next few years regardless. Maybe you should consider being a vegetarian. I highly doubt there will be meat on the menu if you're raptured or whatever.

Extraterrestial Aliens are present and we don't know about them. Nowadays studies are going on outer space living objects. You're not incorrect. There are evidences & proofs of people talking to aliens coming from outer space. "They resemble people in an underwater costume." They were not in a state of hallucination or something like that. Some people are stubborn because of old sayings of grandparents that don't believe them. If people believe unwanted & disturbed souls, ghosts and all, what's the big thing inbelieving in them.
People won't even believe in Souls which are written in religious and books about unexplained, then how will they believe aliens.

i think that people are not being stubborn so much as refusing to credit the ideas of little green men, suspending judgment as it were. you're absolutely right about a multiplicity of planets and galaxies (universes I'm skeptical about) but you underestimate the complexity of components needed to sustain life. from what scientists currently know, even if you end up with a planet that's a viable size (earth is really quite small) then you need a sufficient atmosphere, light, gravity, pressure, and hundreds of thousands of other things to even move to "primordial mud" stage. the chance of all of these things occurring in one place is really quite minuscule.
by the way, there are far more than 1000 planets in the universe and religion largely assumes that earth is a "chosen" planet.
still, believe what you want. i'm just presenting a possible argument against extraterrestrial life

You are right, only the religious whackos REFUSE to consider the possibility that there is other life in the universe. I like your observation that maybe the aliens have their own God who created them.... That's good stuff, and I would say very politically correct.
An astronomer in the 1980's calculated the probability that there are other planets with intelligent life in the universe, using the number of planets in a star system, number of stars in a galaxy, number of galaxies in the universe, and it is almost a certainty that there is intelligent life in the universe besides us.

Why is it necessary for some people to try so hard to convince others of something they believe in, especially when there are no facts to prove or disprove there beliefs.
Is it possible there are aliens? maybe
If they exist at all! Why would they visit? It is very unlikely they would have any idea we even exist. Our technology is way to young for anybody to have detected us yet and why would any being with enough intelligence to travel an unimaginable distance (if that's even possible) travel here without validation of somebody being home.

I agree with you. The universe is just too big to have just one civilization. There just ought to be some other forms of life somewhere in the universe besides earth. I'm almost certain that somewhere in the universe, some life form is asking the same question about aliens ;)

Most thinking adults would agree that it is very likely that life exists on other worlds. And just as likely that on one or more worlds are civilizations more advanced than our own.
The problem comes when people (including yourself) assume that intelligent life on other planets naturally means that they have visited earth.
The two don't necessarily go together.
There is no scientific, concrete evidence or proof of ET visitations to earth.

While I agree that the probably of extraterristial life, even intelligent exteraterristial life, I do not think they travel light years to come to earth and cut up a few cows, or grab some guy in the middle of no where to probe him.
Nope, if they were to communicate, they would be a lot more pubolic about it.
