If there is Alien or UFO visiting earth, under current physics science law, the faster moving speed is light speed, but we haven't discover any planet within several thousand light year away except the solar system.

So either Alien can travel in light speed and they have very long life, or can travel beyond light speed (which dismiss Einstein's theory). So in order to have Alien or UFO, we needs to have either one of it, so that they can reach here.

I am not saying there is no alien existing or other living in the universe, as universe is so big, so we think it is impossibe, only earth got life, right?
But those could be thoousand light year or even more away, which by any means there is no chance to reach under curreny physics law.

The universe is so big, we can't even get out the solar system, not the mention the milky way galaxy which our solar system is a tiny peanut within, while there are many many others galaxy as well.

As said, you need to throw the current physics (light speed in the fastest moving speed can achieve) into dustbin in order them to travel to earth.

I don't say they can't, just we have to rewrite a lot of physics law currently we have if there is.


Regarding ET. Why must every imagination of ET must have eyes, big head, body or a pair of leg? Ain't it is mimic or human imagination only?

Even on earth we have six leg insect, multileg insect, no leg reptile (snake), eight leg octopus, so many many kind life form, why must everyone think ET should be identical to human kind.
It can be in a lot of form if there is a life out there!

It could be because one told the story, then the rest follow the story. In my humble opinion, it is more a human imagination, big brain because they are clever, small limbs because they are smart until don't need physically muscle.
This ET form/build only emerge in 90's if not mistaken, ancient people never talk about or had any history telling what is ET or how ET looked like.

Why must brain at the head? Can be no brain, but nerve interlink across just like jelly fish. Why must they breath oxygen? it is possible to live on carbon dioxide as well like plant.

The way ET being described, it just means people cannot think out of box and everyone just think it must identical to human kind but just different here and there.

Don't mean there is no ET (I also believe there is in somewhere outer space far far away could be million light year), just in my opinion, it is hard to believe universe is so big and every planetory condition is different and there is potential variety of life form as showed at earth as well already. But somehow ET is similar to human kind? which is something is hard to believe, as it is more like hitting a lottery of this probability at least for my view.

B-2 stealth bomber looks like a flying saucer as well.

We have higher chance that earth being bombarded with asteriod causing human kind of extinction than finding UFO or alien visting the earth.

Even alien is within the same galaxy with earth, milky way, under current law of physics speed on light, it might take hundred of thousand and million of year to reach us.

Human kind have how many year of history? several thosand year, compared to millions year needed to travel, the probability is starting with low point already, somemore, galaxy is so enormous wide, what is the chance alien spotting earth so probability goes even lower.
A thousand year is a relative too small time frame in universe standard.

I don't dispute there are potential life form out there (can be a lot of form, not necessary must be identical with human kind, a head, a body, pair of arm and leg), just the probability of alien reaching earth is not promising at all.

Here come another question, how can they communicate with earth then?

Radio wave?
Ultra-high frequency wave?
Low frequency wave?

If they have the technology, they don't necessary communicate in wavelength or technology we are having now, it could be in other form we human kind don't know yet.

why everyone think alien has almost identical technology with human kind? This is question that always make me wonder, is it human creating or imagine?

As whenever we imagine something, we always use ourself as base form.

I don't doubt it could be UFO or alien or other life form out there, just I have difficult to comprehend alien is identical to human kind as we have so many of probability of living form even on earth alone.

Human kind never understand the universe well until now, a lot of issue have in outer space are not fully understand. So there are some phenomena or happened (moving light or objects) then it must be UFO?

Even on anti-matter issue and origin of this universe and earth forming is still not fully understand until now.

UFO = Unidentified Flying Object.

It doesn't necessary must come from alien, it can be another aspect/ phenomena in universe we are not understand yet.

The most important obstacle for alien contacting with earth, be it RF, EM or whatever type of communication form is distance. As if alien is also subjected to current what law of physics current we have, it needs ten of thousand or hundred/million thousand of light year to send a signal to earth, while spotting earth in the vast universe is no different than finding a needle in a big deep ocean.
Human kind has how many of history, much much less than that. Human kind existing period/history is not enough for sending or for the signal to reach earth what's more is that finding a tiny earth in the universe.

So chances are very very slim even if there is alien out there.

To imagine other lifeform in other planet or galaxy which is identical to human built (head with brain, a pair of eye, body with 2 arms and legs) even creepy/weird.

UFO is surely there because UFO = Unidentifed flying object.

As long as you see an object in the sky that you can't identify what is it, then it is UFO.

Comet rain is also an UFO for ancient people.
B-2 stealth bomber was an UFO for 80's people.

We don't want the term UFO, we want solid concrete proof or AFO (alien flying object)

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.

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.

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.
