Is there life on other planets?

Question

I have been open minded to the possibility for a long time. Why not. But some of the programs that I have seen on T.V. in the last year or so has made me a little uneasy. On UFO files the one about the black box recordings is scary. Some of these sightings were so long ago that there could not have been anything here on earth to compare to what has been seen. Also the USO programs are compelling too. I think that they are out there. There has been more and more info released for public viewing. Are we getting close to an "event"?

There are always wormholes. This may sound like science fiction but much of what was once science fiction is now reality.

Answer 1

i think there is but true science isn't looking for little green men. lets find microscopic proof of life then go from there.

Answer 2

Whether there is life on other planets, that is hard to say. I'd like to beloeve that there is. It's hard to believe sometimes, that Earth is the only planet that by some weird coincidence or the perfect alignment of a series of events was able to sustain life. As for UFO's, there have been tons of documented cases and who's to day that some of the people out there are actually telling the truth? Not everyone is a liar. People all the way from the ancient times wrote of objects that flew around in the sky, and they said that they were watching them. Creepy, huh? Well, there may be life and there may not be. Until you see proof of the existence of UFO's or extraterrestrial life, it's hard to really accept it, because it may not be true. I'm very open-minded and like to believe that there is other life out there, but what of there is no such thing as UFO's? Just because you believe in it doesn't make it true, and just because you don't doesn't make it false. Well, that's just a thought. If there really is life on other planets, I don't know if we'll ever find out, in our lifetime anyway.

Answer 3

Look at it this way. There are millions, if not billions, of galaxies in our universe. Each galaxy has a few million stars. Each star has a few planets. To think that we are the only life in the entire universe is a bit egotistical, don't you think? But the universe is so vast that it may be a few millenia or even longer before we see any signs. A light year is the distance light travels in a year. The nearest star is four light years away. That means you are seeing the star where it was four years ago, because that's how long the light took to get from there to your eye. We can't go anywhere near the speed of light. So we may spend our lifetimes never knowing, but I'm pretty sure there is other life out there somewhere.

Answer 4

Your basing your responses on what we have learnt from science here on earth.
Science here can not even comprehend everything on our blue marble let alone what is going on else where.
Some minds have theorize what's out there, but you have to also take into account what might be taking place here in the future, or some of what has taken place in the pass.
If there is life, why would they not be far beyond our abilities to protect them selves from detection. In other words, our militarizes have long researched the abilities to be undetectable. So in reason why would other life forms not research the same things. Especially if they where going to travel through space to far distance planets.
The theory to conquer a planet or species for that matter is without merit , as these life forms would have knowledge we have yet to achieve.

Answer 5

Why would you think that there is not life on other planets?
Science estimate that there are millions of planets. We can't be all alone in the vastness of space. UFOs in the 70s knocked out all power in two missile bases rendering them useless. UFOs were in the news all over the world when they invaded the air space around Washington D.C. in August of 1952. There are paintings of objects that look just like a saucer out of a sci fi. movie in caves thousands of years old. Even glifs in Egyptian tombs that look like UFOs. Paintings in the middle ages showed flying objects in the sky, and there are events in the bible that easily could be seen as UFO visitations. I would hope that the world will soon know of the truth. I agree with you if people saw them before the airplane then they couldn't be secret planes.

Answer 6

There simply has to be life on other planets.

The most common element in the universe is hydrogen and all it takes is 2 hydrogen molecules and 1 oxygen molecule and you have water. We have determined that water is the essential factor for the existence of life as we know it. Where these elements occur together it is extremely likely you will find life and the single function of any and all life is to "evolve".

As for alien visits to our planet.... Forget all the hype you see on the internet and other sources. It's way too easy to fake any of that stuff and most if not all of it is utter garbage. The big problem is that somewhere in this plethora of hoaxes and fantasy stuff there could be the genuine article but there's no way we can discern it from the guff.

Answer 7

Forget about UFOs. No matter what you've seen or heard, it's ALL hogwash! If aliens had found us then they would be wise enough to know NOT to interfere with emerging intelligent life forms (similar to the way we try not to interfere with nature when we film our documentaries).

As for life on other planets; ABSOLUTELY! The fact that there is life on OUR planet PROVES that life can exist on a planet and there are BILLIONS of planets (WE ARE proof of life on other planets!).

INTELLIGENT life... that's a whole other proposition.

I'm of the opinion that life is one of the easiest things the universe can make (it does not take much at all for life to spring forth) but INTELLIGENT life is infinitely harder... We are either a mistake (a glitch in the universal design) or just one of a very rare occurrence of self-sentient life.

In that case the chances of two intelligent life forms evolving on two planets in close enough proximity and within the same universal time frame to actually be able to find one-another are astronomical!

Using those odds there may be (generous guess) two or three other intelligent life forms in our galaxy and for any of us to be at a similar simultaneous advancement to actually communicate seems unlikely.

In short, the answer to your question is; YES, DEFINITELY but it won't affect us...

Answer 8

Oh, there's definitely life on other plants. It's not feasible to say that there's not. What some people don't realize is that there are billions upon billions of galaxies, and we inhabit just one of those billions! There's also billions and billions of other planets. It's ridiculous (and also against the odds) that we are the sole planet with life in this universe filled with a trillion galaxies & planets.

Life on other planets have probably evolved in very different ways. We can't know for sure their limitations and how advanced they are. Other life forms may also be able to survive on planets that the life on our planet would find inhabitable. It's possible that life on other planets AREN'T composed of carbon and etc.

I do believe there are other planets in this universe with life. As far as little green martians or grayheads, I do not know. It may be true, it may be not. Whatever shape or form other existential life takes, it exists. It's virtually impossible for it to not.

Answer 9

The question of whether or not there is life on other planets is a complex one. It is likely that the answer is "yes" although it's also likely that we are quite far from being able to discover such life, and we are still far from being able to conclude that the answer is "yes" with a reasonable degree of certainty.

On the other hand, a lot of the stuff on TV about UFO's and such is nothing more than conspiracy theories, people acting out fantasies and dreams.

Why do I say that it's likely that there is life on other planets? Initially, a lot of scientists viewed life as an "accident", the idea that molecules spontaneously formed that become complex enough to eventually evolve into the cells we are made of today. But now, people are starting to view life as much more "natural". For example, one scientist showed that if you mix the basic elements of the primordial earth's atmosphere together, and give similar conditions to the conditions on earth at the time, amino acids and other complex molecules will spontaneously form. This experiment is reproducable--it does not depend on an "accident" or chance, but rather it works every time.

Scientists have also developed theories about how cells formed, and again, they have found that the formation of cells is fairly natural and happens spontaneously under the right circumstances--it's very similar to the way soap bubbles form in water: large molecules that are polar (water-like) at one end an non-polar (oil-like) at the other end will spontaneously form cells.

Life is not just cells and information coded in complex organic molecules--but it's also cycles of energy and nutrients. Just like we eat and then give off heat and waste products, early life forms would metabolize chemicals in their environment, in constant cycles. But the amazing part is that some of these cycles of reactions will exist even in the absence of life. In this respect, the formation of life can be seen as a natural organizing of the cycles of chemical reactions that existed in this "primordial soup" of organic molecules.

There is a lot of evidence that the environment to create life exists on other planets besides Earth. Through spectral analysis of light, we can detect chemicals in far away places, and we have detected some of the simpler organic chemicals outside of earth. Also, meteorites have been found to contain organic chemicals that likely did not originate on earth.

Most people look for the presence of liquid water to indicate the potential for life to evolve. Recent studies show that Mars may still have liquid water, and it is virtually certain that it had it in the past. We may even find life on Mars during our lifetimes! There are other bodies in our solar system that may have liquid water, such as Jupiter's moon Europa.

Some people have even speculated that life could exist without water, for example, in ammonia, methane, or other liquid substrates. Again, this sort of life could possibly exist in our own solar system! Saturn's moon Triton may have liquid methane in it. People have also speculated about the possibility of life in a gas giant; we know very little about gas giants, so it is difficult to rule out the possibility of life there, although if life exists there, it is probably very different from what we know of.

Answer 10

One might say, (looking at water for the first time,) that there can't possibly be life, that can breath this stuff. Maybe there is life that has evolved elsewhere that can breath in sulfuric acidic air, or be where we call too hot. We have evolved to be able to breath oxygen, and drink H2O. We are strange Carbon based creatures, with bushes growing out of the top ends, and appendages that have scales on them, and orifices that make squawking noises!

Answer 11

Well possibly. Scientists have come to know that there is life other planets (cells, bacteria, and all those small things). Sooner or later those will evolve to be living organisms. But it takes time. Since the universe is so old the evolving process probably has almost completed therefor making the universe have some sort of life.
