Do you think that there is life on other planets??

They wouldn't have to show up here. Well, we could also show up at THEIR planet and find out! In fact, we wouldn't even have to show up, just send a satellite close enough (or just have continually better technology to tell what's out there from our current vantage point). The likelihood of finding life shows much better promise than it did many years ago because we have found out that life-creating conditions in our corner of the universe are much more common than initially thought. However, statistics also tell us that most aliens would likely be micro-organisms anyway. Oh, and there is the possibility for life to thrive in sulfur, which would be poison to humans.

Life may have evolved in a totally different direction on their planet that Simian bi peds. Aliens might live thousands of years longer than us or just for days like our May flies. There may not even be sentient (self aware) life on other planets longing to travel the stars like us. Maybe they are happy right where they are and so feel no ambition to leave their planet. There is evidence that the other planets in our system may have been very different from how they are now over their evolutionary cycles. There is even oxygen, in very thin and small quantities on a coupld of the planets in our system. Aliens may not be oxygen breathers which means that they will never come here for a "visit" since they couldn't breathe our atmosphere.

They could be friendly and interested in our existence because for centuries they posited that there was no other life out there either. Or they could be seeking planets to suborn and take over due to the using up of their own resources on their planet. We won't know until they arrive. But taking and dissecting them would be the aim of any human that they came into contact with and in most societies, whether they are hyper technologically advanced or not, if you take and dissect their people when they come to visit that is an act of was or at least of savages and you know that that could probably start a war.

poingly has a point when we find them or they find us whichever comes first we will then have definitive proof that there is other life out there. However borg I believe the same things that you do so there was nothing unclear about yoiur response. I think the governments of the world, heck the people of the world are scared that there is life out there that is more technologically advanced that is going to arrive one day with conquest in mind. However a space expedition that reached here would more than likely be a small one and one of science and discovery rather than a mission of conquest.

Wouldn't it be completely answered if we actually found aliens? (Or if they found us?)

There may or may not be life out there, but it just seems crazy to think that there isn't anyone out there but us. Why would God or whoemever is running the show make an infinite number of planets and then only put life on one of them. That idea does not hold water.

I have often thought the same things. That there may be aliens out there with powerful telescopes, watching us hop back and forth between our moon and the planet and rarely venturing any further afield, laughing at our tiny efforts to actually explore the stars. We may not have anything that they either want or need which is why they don't bother much with us. Or the way that we are willfully destroying our planet and ultimately ourselves.

I agree with you completely that there is extra terrestrial life out there. They may or may not have discovered how to trabvel between star systems or galaxies. There could be as many extra terrestrials as there are little blue balls of gas out there. Until we manage to get out there we will never know for certain.

They don't have to be more technologically advanced than we are to be out there somewhere. We are not all that technologically advanced either hopping back and forth between our moon and earth and sending out unmanned probed and telescopes to the other planets. There is little or nothing known about most of the planets that we have located that are outside of our solar system. Alien life forms in other parts of the galaxy may question whether or not we exist or not. It appears as though we haven't developed interstellar travel capabilities and it is possible that neither have the other life forms in other parts of the galaxy. The galaxy holds an infinite number of stars with planets in close enough orbit to sustain life. Just because we claim there are only a handful of planets that are close enough to their stars to sustain life doesn't mean that creatures who require a different atmosphere and temperatures cannot live on any one of the planets out there. Even if their atmosphere is largely frozen water like Jupiter and Neptune. Thank you for responding to the discussion.

Firstly I am a Ms. Sharon e, secondly any website about life on other planets asks the same question I have posed to you. Everyone wonders if out there revolving around some alien star similar to our own there is life that has sprung up in the right circumstances just as we have. I didn't ask if there was life on other planets in our Solar system. I think you will have to ook far beyond out tiny little star system for life and that means a very very long trip to get either out there or back. It would take a 1 mile long ship with a speed measeured in miles per minute, or thousands of miles per second, 6 years or more to reach the boundary of our solar system and it would have to figure out how to get through the ort cloud out past Jupiter without being detroyed before we can even get out of our solar system. We don't have that tech yet and getting through a cloud of asteroids and space debris which is the ort cloud without being struck or crushed is impossible even if we could build the right ship to take us out of here on. Check out some of the vids on youtube.com about space, the solar system, the hubble telescope images of the universe, the sounds of the radio waves coming off of Jupiters rings, or what we have learned most recently about the 8 planets in our little tiny solar system. We know more than ever about the planets in our solar system than ever we did and still they wonder if there isn't some form of life on one of them that is unaware of us and takes a totally different form than we do.
