UFO = is just a term for unidentified flying object.. let said aeroplane, u did not know is aeroplane then aeroplane = UFO.... simple....

actually, we r alien... Y? if u r alien, then u see human so wat would u think... ALIEN.. As we see other species, may be their species name called AVATAR... then we did not know.. so we said them ALIEN....

Categorized = ALIEN - Human, ALIEN - Avatar, ALIEN - Transformer...

i believe ET does exist..... we r not only in universe... y only earth can sustain human species to lived... y not for other planet... we aren't know..

Science is only need something to proof... but some really cant proof.. let said GHOST.... did science said GHOST is exist?? Science is human create.... i mean theory, technical ,etc... like calculating, formula..

anyone know, actually we did sent a lot messages to universe about our exist... like voyager probe.. voyager probe got our human voice, etc..

Those are considered trivia, super macro tiny in universe term.

Just like try to find a dropped needle in ocean.

Set aside whether there is ET, alien or UFO issue, even finding earth in the vast universe scale is like 1/1,000,000,000,0........... chance.

While existing physics theory mean distance travelling is also impossible, we might see distance star away, but we cannot possible contact, or communicate with them (if there is ET there), as for any information/radio signal to reach there, means several thousand year has passed. <-- don't know human kind still exist or not in earth by then.

yup, this is y we cant get proof of ET does exist.....
as we know travelling is impossible because of distance but wat bout roswell incident happen?? kenneth arnold witnessed? n Y we always draw the ET face is big black eyes?? y dont we draw a dinosaur face n human body or kangaroo face??? since we did not know....

For Roswell incident to be a real ET, as I justed posted, it could be 1,100,000,000,000,0........ chance of it is real.

Any drawing of ET is more like human imaginary picture. Why ET cannot be like Doreamon? He also got big eye, big head as well.

To be ET as like as human body structure (most ET drawn picture has a pair of leg and had, as same as human except bigger eye and brain), it will be another 1,000,000,000,000.... chance. Even in earth, we have various form of living creature, from no leg, 2 legs, 4 legs, 6 legs, 8 legs, multiple leg creature around or even fish type. Earth is so small already got so many variation, sometimes I find hard to believe ET is as same body structure as human kind. Bare in mind, human kind structure is not the best or in fact worst than most creature naturally in term of surviving the environment.

So with just 2 simple fact, we have 1/1,000,000,000,.... x 1/1,000,000,000,..... chance of the ET is real in the incident.

I am not saying there is no ET, I 90% believe, there would be living form elsewhere, but to contacted with earth, reached earth and as same as human body structure is something not easy to believe.

Possibly by the time we come in contact(a radio signal) with another civilisation, they could already be extinct. A last message from a dead civilisation.

Yes, this is what I keep on trying to highlight the issue, human kind individual life or even human kind existence history (several thousand years) is simply too short in universe scale.

So by then we received or ET received our radio signal, it is several hundred thousand years has passed. To get a signal from ET within several ten years time, it is another 1,000,000,000,000..... chance.

If one is well verse the statistics, the probability to get a ET signal and come in contact with ET, the probability is too trivia until become almost zero.

Do remember, finding a distance stars is already difficult enough, it is even harder to find a planet, as planet doesn't shine like star, you actually cannot 'see' a distance planet.

yup agree.... as what we see in dark sky... de star may be is dy dead for long years ago.. but the light just reach earth....

I don't think UFO harms human,
I think they visit earth in a good way.

I heard the future saying that,
UFO those aliens are those who stop 3rd war
and save our earth from being demolished.

Mind to explain about the bold part?
It seems like you took this story from some Hollywood movie.
No offence.

i believe there is life out there in the universe, but the odd of us ever making contact with those life form will be so rare that it is unlikely we will ever meet them. even if we does meet then they may not be anything we imagine they are like in popular science fiction movie, i will be unlikely to meet another carbon base life form that happen to develop technology high enough to reach earth.

even if they reach earth they may be so much more advance then us that they may have no interest at all in meeting us, like if you see an ant will you take it back home and teach it the knowledge of human being?

The odds will be much better if we manage to extend our lifespan(this possibly also means outliving out sun, our homeworld) and not destroy ourselves. Maybe intergalactic space travel is extremely difficult where maybe not many civilisations(or none at all) can manage to achieve it.

Even so, the promise of exploring the cosmos is a tantalising prospect which I think we should endeavor to reach. But we have to leave behind our destructive ways.

exploring the cosmos require significant amount of investment over a very long period of time, when ever there is recession the space program will likely get budget cut because it is view as non essential. that is the biggest challenge to space exploration, there is no doubt that there are many talented people working on space exploration but no enough resource are being provided.

Yes but we are talking about a huge timescale. Don't see 50 or 100 years. Maybe 1000 years. Of course local issues need to be solved. Energy crisis, dwindling resources, poverty, politics, income distribution, human rights(lets face it, we may be the most advanced species on this planet, but we haven't advanced enough to treat others of our own species well enough).

Eventually science should find a breakthrough. It doesn't have to be in the field of astrophysics. Other scientific fields can (and have always) contribute to our ultimate goal. Of course we'll have to 'survive' on this planet, from ourselves to reach that point in the first place.

The best concept to view is Kardashev scale
Type I — a civilization that is able to harness all of the power available on a single planet
Type II — a civilization that is able to harness all of the power available from a single star (e.g. Sun)
Type III — a civilization that is able to harness all of the power available from a single galaxy

So where are we??? We're still just Type 0 civilization as we still depend on fossil fuel
So we need science to move humankind to Type I civilization

i believe UFO does exist in our universe... we really not alone....

but because of timescale n distance... n policy of our human civilization.. political issue...

that's y, what we always hear is always HOAX...

UFO could be attempts of develop advanced aircraft or spacecraft in nazi germany prior to world war II that lead to minded ufologists
