Is there another world that life exists?

Question

Is there another planet that life exists? Are there life forms greater than us, as Steven Speilberg speaks? Are UFOs a fact or a fiction? Are there real evidences that life forms [aliens] from outerspace exists? are there sitings about this so called aliens? Or all of these are just a mere imagination of a human being?

Answer 1

It's hard to answer that question, as we haven't explored any planets other than Mars, and then it was a very superficial, mechanical inspection rather than a full-scale exploration.
We also have to define what 'life' is. Is there another planet with life forms identical to those we know? Highly unlikely. Just look at how evolution has changed life forms from one continent to the next. If there is that much difference on one planet, how much greater could the differences be on a planet with a different gravitational field, a different magnetic field, differential types of soil, etc.etc.etc. It's quite possible that we could send out an exploratory space rover, fly over a planet that did have its own life forms, and not even recognize them as such. There is also the possibility of underground colonies -- not too far fetched if you think about ants, who live in just such colonies on our planet. If life developed in an area where harmful radiation was present, it could well have moved underground, and we'd never even know it was there. This doesn't even begin to address the notion of intelligent plants, spores, fungi etc.
At present, we have very few hard facts, but there possibilities are tantalizingly endless.

Answer 2

No one really knows the answer to this question - nor CAN anyone truly know the answer.

If I had to make a guess - I'd have to say yes - simply because of the vast size of the universe.

However - there has never been any scientific, document proof that UFOs/aliens have ever visited our planet (and this is the only type of proof I'll respect).

Additionally - learn a little about not just the SIZE of the universe - but just how far away we are from other solar systems and galaxies. Then think about the amout of time it would take to travel from one solar system to another searching for life....

The simple truth is, you will quickly come to realize that we are simply too far away to ever be reached or to ever go anywhere ourselves.

Unfortunately for the curiosity of the human spirit - it's a question that will always be asked - but will never be able to be answered with any certainty.

Answer 3

We have found that life abounds through-out the galaxy and we assume that the same conditions prevail through-out the rest of the universe. We have been visiting your planet for a long time. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species and your infantile,(in cosmic terms) dependence on god concepts does not bode well for you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

Answer 4

I always wonder about such things. Can't exactly say about their Real Existance. May be somewhere in the Univerese there is such a planet or are some planets where beings (aliens), just as we are human beings here on this earth, are living.

Well, I think you should try to study about it. I mean some Scientific Research studies can give you more exact ideas about aliens. I am very much inmterested in knowing such things! :)

Answer 5

I really believe that we aren't the only life but are the only sentient life. When thinking about it life has existed here for billions of years yet sentient life has been around, to our knowledge, for a couple of hundred thousand years. This appears to be so because of the number of times that evolution has had to restart in order to get here. We still have a long way to go to get to the traveling stage and probably won't make it. We cannot get past our warring and uncontrolled use of atmospherically harmful elements.
UFOs and extraterrestrial life are fiction.

Answer 6

Life exists elsewhere. The world is infinite. Therefore there are an infinite number of planets out there with life on them.

I really doubt we found alien life forms as so many goof balls think. There are just too many reasons to open that discovery to the world.

Answer 7

Personally i can not say that there are definitely life forms called Aliens. If you think about it, the human race got here how. If we are here than there might be another place where something is. Unless they show their faces to the Human race, we will never know nor will we ever prove it.

Answer 8

Of course there is. How logical is it that in the vast expanse of the universe we are the only planet that supports life? I tend not to believe all the yahoos out there who get say they are repeatedly abducted from their trailer park and subjected to probes, but if there is truly no other life out there isn't it an awfully big waste of space?

Answer 9

I would think it's literally IMPOSSIBLE for life to only exist on one planet in the universe. To argue otherwise indicates a lack of respect for the incredible size of the universe.

Answer 10

There probably is life on other planets that is just a guess by the law of averages. The only proof that we have is microscopic fossils from Mars. Other than that it is only speculation.
