Is there existence of UFO's and ALIENS?

Question

Many scientists were believing that there is existence of aliens and ufo's. How it will be? What will be there color, size and shape? Did any one saw that? Why no one is sure about that and proving that?

Answer 1

So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.

Why haven't we heard from them?

Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.

Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.

Perhaps they are so far away they will never notice us and vice versa.

Perhaps they existed a million years ago and died out.

Perhaps they will exist a million years from now.

It is really impossible to know for sure.

The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

Answer 2

Aliens may exist, but we would never or have never seen them. The closest star is 1 light year away (give or take) IF that star had planets and IF a planet has beings, and IF they developed a way to travel to Earth, a number of things would get in thier way.
1 - they would run out of fuel before they got here, assuming that they found a fuel efficient enought to propel them through space for such a long period of time.
2-if they managed to overcome #1, they would be racing against the clock, so to speak. Space travel doesnt happen at the speed of light, like in star wars. It would take them 100's of years to cross all that distance and would be dead before they got here. unless they lived to be 800, like yoda.

and that is the closest star - forget about ones further away.

Answer 3

People think life cannot exist on other planets because the basic necessities are not present but my question is WHY???
it may not be necessary that what we humans need, those things aliens also need for survival....there even can exist life on the sun why???because those organisms mat need heat to survive.....why should we not change our thinking??? I strongly believe there IS LIFE IN OUTER SPACE
and then again this universe is endless it has endless galaxys the galaxys have endless planets on those planets atleast 1 planet may be like earth RIGHT???

Answer 4

AH, a semi-intelligent young lady, FINALLY!!!!!!! I believe there is proof. The united States has this place in the desert called hangar 18. It is said there are alien bodies there, as well as spacecraft from other worlds. I firmly believe there are aliens, A great book is called 'chariots of the gods by Erick Von Dani ken] read it! It's pretty interesting!

Answer 5

UFO's and ALIENS are a big challege for astronomers for about half a century. Nobody has proper evidence to prove UFO's and ALIENS exist. So it has remained a mystery.

Answer 6

No one is so sure of it bcoz,they didn't see it for real....As far as our space research we haven't found anything....scientists r sreaching for traces of water in Mars and so far has found some traces on the south pole of Mars...........but still the theory goes on of other existing life forms.......may be in some corner of our galaxy there r aliens, may be they r far more capable in science than v r right now......well my frnd my imagination runs wild......Hope our scientists discover something fast....

Answer 7

this could be a stable question! It rather made me think of, I had to massive call it and are available lower back lower back later. :) it is not ordinary for me to compliment yet i might might desire to assert the afterlife. My reasoning is that i think of that extraterrestrial beings (a number of them) are linked to the afterlife. There are theories that Angels and extraterrestrial beings could be one interior a similar and that i might want to confirm if it extremely is authentic. If that grew to become out to be authentic, then i might understand approximately the two issues, the extraterrestrial beings and the afterlife. :) the only secret left could be various the unidentified flying merchandise guidance using fact I doubt all of it's the artwork of authentic extraterrestrial beings....a large style of it is possibly government/militia correct.
