Do you think they exist? What do you think they look like? What about UFOs? I believe it's almost impossible that we are the only ones out there... the universe must be pretty big, and somewhere out there there's got to be something. And I think that something would be really small... as being small has numerous advantages - you don't need as much food, shelter, etc, and I also think it would be silver and shiny as surfaces with these properties reflect heat best, and this would probably be quite useful in space and stuff...

I believe in the possibility of aliens. I find it hard that we're the only planet w/ life in a universe so vast, but i've yet to see definate proof to alien's existance.

I do believe there's intellegent life out there, but I don't think they have come to Earth... Yet.

Yes, I believe in aliens. I mean, the universe is HUGE, there's no way we're the only ones. Each star is a sun, and on at least on of those suns there has to be a planet around it with other life forms on it.

I believe in aliens. Our solar system is soooo tiny in the entire universe. There are billions of stars of the same size or bigger than the sun, so there is absolutely *no* way that there isn't life on at least one other planet. [shadow=limegreen,left,300]~*Esther*~[/shadow]

I believe it's quite possible.
It's hard to believe within this whole huge universe, that supposedly goes on forever, that Earth is the only planet that has the ability to sustain life.
Have there ever been any aliens to visit Earth? I have no clue. It's pretty freaky to think about. But I do not think we are alone. There's a chance, but I believe if you really think about, the probabilities are that were aren't the only ones.

I do believe that there's a possiblity of intelligent life out there somewhere. It's true that our earth is very small compared to this universe. It's almost hard for me to believe how big the world is...let alone the universe! ;D

There may be life on other worlds but not much more than plants, algea and bacteria. Even as vast as space is, the conditions to support life as large and complex as intelligent life have to be just so. If it's too hot, the DNA just falls apart. If it's too cold, metabolisms can't be maintained.
Same with a planet's atmosphere. It it's methane, very few kinds of bacteria can live there. If it's chlorine, forget it. Look at our own solar system. Mercury is hottern'Hell so that lead boils. Venus has 900 degree heat, a corrosive atmosphere, and crushing gravity. DNA would not hold together. The Earth is perfect, just the right distance from the sun with the right conditions to sustain life, even in hot springs, or below zero cold. <br> Mars: The atmosphere is too thin and a balmy day at high noon is 30 below. The air is so thin that wind blowing at 100 miles per hour is barely noticable. Yet you'd get the ultimate sunburn on Mars. Jupiter is a star that failed, probably true of all the gas giants. The moons of Jupiter and Saturn are too big, too small, not enough gravity for the right atmoshere, not this, not that for any kind of life. And the verdict is still out whether Pluto is still a planet or just a chunk of rock that vegged out in somekind of orbit.
So now we get to the rest of space. Almost every planet outside of our solar system that's been discovered has been too large, or too close to a star. If the planets is too large, the gravity doubles and triples, maybe more. It's obvious what happens when the planet is too close to a star.
Then we have the stars themsleves. Our sun is a certain type of star. Just the right size and stable. It's not a variable like the red giant, Betelgeuse. A star the size of Earth's orbit around the sun. Sometimes it flares up and is the size of Jupiter's orbit. Other stars are red dwarfes that shoot out solar flares big enough to fry planets as far away from it as the Earth is to the sun. White dwarves, which are burned out stars. A planet orbiting a double star would have huge swings in climate and temperature, that is, if its atmosphere isn't boiled away while it swings close to one star, then turns into a chunk of ice while it swings away from that star on its way to the other one.
A planet orbiting a Supergiant star wouldn't have time to have life develop. Take a blue supergiant, another solar system-sized star. The starlight would be intolorably bright, you couldn't look up, ever. Your shadow would have a razor sharp edge. Then in a few million years, all the fuel would be used up and the star would explode in a supernova that would destroy the rest of it's solar system.
Another thing to think about: We've been sending out radio signals for over 100 years. We've been sending out TV signals for over 50 years. We have been specifically broadcasting to "aliens" for at least 40 years. Think of this. There is a bubble of all the radio and TV broadcasts from every country in the world, recording every event that has happened as long as these mediums have been around. <br> This bubble is over 200 light-years wide. Big enough to surround some major solar systems. No one has responded. We've never picked up any broadcasts or messages from anywhere else than from Earth. Where are they? There's certainly been enough time for responses. <br> As far as UFO's. There are huge limits on what spacecraft can do. Just accelerating to nearly the speed of light will crush the occupants of a spacship, if it's doesn't get shredded by the little meteorites and dust in space.

I believe there is life out there. Earth is the perfect place for us because I think we kind of evolve (is that the word I'm looking for?) into what would keep us alive on earth, and maybe it is the same way with other living things out there. Just because our kind of life wouldn't survive under those conditions doesn't mean another kind of life couldn't... Well, I know what I am thinking, but I can't get it into words... and I don't know that much about the subject so anyway...

^ I understand what you mean, I was just thinking that too. Just because our bodies aren't fit to live on another planet, doesn't mean that there is no form of intelligent existence that is fit to live like that. We evolved into this so we need oxygen, this temperature, etc. But if we lived on some other planet, we could have evolved to be able to survive there... And besides, who says that this is the only planet with this temperature etc.? ~*Esther*~

Except that if it's too hot, DNA falls apart. Too cold, and metabolisms can't be maintained. It doesn't matter if you're a carbon based, silicon based, or any other element. If the conditions aren't just right, life cannot exist I don't care how diverse it is. The bacteria that live in hot springs and inside glaciers are close to death anyway.
Take a look at the way aliens are thought to look like. The big eyes and long fingers. The big eyes are not for looks, that suggests a planet with very low light. Low light, probably cold as hell and that would reduce the chances further of a culture advancing much past cavemen. The long fingers get in the way, they are not good for dexterity. In fact the long fingers would be a hinderance, not an advance.
And since these alins are thought to exist, where are they?

I definitely believe there is life on other planets. The universe is enormous. It is impossible to comprehend how huge it really is. The idea that we are the only planet in the entire universe that has forms of life is incredibly self-centered, in my opinion. The only planets we know enough about are the 9 that are in our solar system. Maybe life couldn't exist on those planets, but I'm sure there are others in different solar systems. Also, some people say that life can't exist on other planets because the conditions aren't ideal. Well, they aren't ideal as *we* know it. It's also important to remember the state of our planet when it was first formed. For the longest time, it consisted of molten rock. However, micro-organisms were formed during this time, and they were able to evolve into more complex life forms. For all we know, a lot of planets out there may have micro-organisms that someday could evolve into intelligent species. I'm not sure if there is intelligent life out there. If there is, we may never know. They, like us, may not have the technology to find out, either.

I believe in life outside earth. Intelligent life, not just strains of bacteria. The universe is so vast, whoare we to say that life can't exist away from home. That attittude is so typical. Humans put themselves at the centre of the universe... as usual.
Isn't it interesting how the ancient civilizations in Egypt, S America and Asia just sprang up from no where and then disappeared? Ever stopped to consider if these were really aliens come to earth, to teach everything they knew to this primitive world, and then left? Isn't it worth considering, looking at everything these civilizations had acheived? What these people developed still are ahead of us in some areas. Maybe aliens came to earth to teach us philosophy. Maybe angels are aliens. Who knows? It is highly likely that these advanced beings wanted to spread their knowledge.
Toxic, your description of aliens is so stereotyped. That's the Hollywood, 'humanified' version of aliens. Why should they resemble man in any way? The way we imagine the unknown is too human. They don't need to have two long 'legs' emerging from a 'waist'. Why should their central nervous system have to be in their head? Why should they even have a head? For all we know, they may be able to change their forms constantly.
Man is (nearly) always afraid of the unknown. Maybe now the aliens are afraid to come to earth. Fearful of a bad reception from us. Maybe this idea is based on a past experience that has been covered up and kept away from our knowledge. The thought of something more powerful than us has always frightened us. The only difference is, the ancient people were ready to accpet and even worship superior beings/things (think fire, rain, sun, witch doctors), whereas we want to shun it and pretend it doesn't exist.
