do aliens exist?

Answer 1

Yes. They kidnapped me and told me their plans. I had to promise to keep it secret.

Answer 2

There are three ingredients required for life like ours.
Time,chemistry and environment.
All these thing are abundant throughout the universe.
DNA would be the result and though it could be a bit different than ours it is probably pretty close.
Intelligent,technological aliens could look like anything out of science fiction.
They would evolve ,think and act like us,and have all the problems that saddle humanity.
The range of intelligence that humans have would no doubt apply to all aliens.

Answer 3

No one knows. Any definite answer anyone would give would be mere speculation. Some of these speculations are more informed than others.

My speculative opinion is yes. My reason is that there are far too many stars with planets that we know of for us to be the only planet to have at some point had the right conditions for life. Life is complex, but the bare essentials of life (a supply of atoms in which evolves a simple, self-replicating chemical species), are commonplace. We may very well be the sole guardians of life down here, but it FEELS so unlikely (again, speculation, not science).

Answer 4

no!!!

Only...
...
..

God
...
You
....... and
me

exist.


just ask the bible

hahahahahaha. thats the biggest crock o crap I've ever heard of.

of course aliens exists. count all the stars you can see then multiply that by a 100,000 then you still have no idea how many stars are out there.
there must be billions upon billions

with that many possibilities even if theres a .0001 % chance in a billion of life in another star system , that still give you the chance of 100,000 systems that could possibly hold life.

aliens have not been found on earth YET, unless you believe the "sightings" from crazy lonely people

Answer 5

There are billions of stars in each galaxy, and there are billions of galaxies in the universe. We already know of several hundred extra-solar planets, so it appears (as expected) that stars with planets are ubiquitous. That means there must be countless trillions of other solar systems in the universe where there may have been planets with suitable conditions for abiogenesis.

Now, there must be a certain probability associated with abiogenesis - Maybe it's unlikely to happen even in a trillion solar systems (in which case why are we here?) or maybe it's only (say) one in a billion, in which case there ought to be hundreds of examples of extraterrestrial life in our galaxy alone, and billions in the universe as a whole.

However, what are the chances that the *probability* of abiogenesis exactly matches the number of *opportunities* it has to occur, so that it happened exactly once, and only once, in the entire universe? This, to me, seems incredibly unlikely - Either abiogenesis would be so unlikely that it would never happen, or it would be quite likely and it would happen billions of times. For it to occur just once, and only once, seems far more unlikely than either of these possibilities.

So... Given that we're here, my guess is that life has started in many other places in the universe too. How much of that would develop into intelligent species is another matter, of course.

The only caveat with this argument involves the idea of multiple universes: Suppose that there are many or an infinite number of universes, all with different characteristics, and that the probability of abiogenesis is so small that it's extremely unlikely to happen even in a trillion solar systems. In that case, maybe there are a vast number of other universes in which conditions suitable for life exist, but it never got started in those other universes - Our universe was the one place where this inconceivably unlikely event occurred, and it occurred only once. That's a possibility that we could perhaps be disappointed about, or inspired by, depending on your point of view.

Answer 6

millions of people around the world have seen a disk shape object..u kno..the crash at roswell new mexico, goverment cover-ups and etc...The goverment is trying everything to keep any UFO related topics as a secret.

I recommend you to see the "UFO DISCLOSURE PROJECT" in youtube. or maybe you can search for it in wikipedia...

Theres life in other planets and there is civilization that is thousands of years ahead of us and also in terms of their technology.

Some people say that religion hold us back...but look, the bible does not mention if theres life out there or not. Its becoz the Bible talks about our relationship with God and about us..so yea.

the Universe is way to big...Billions of Billions of star and galaxy out there and I dont think earth is the only planet that has life..Those UFO's are capable of getting here on earth becoz of their technology using anti-matter energy,enerta counselor,anti-gravity and etc.. well, enough said..

WE ARE NOT ALONE...

Have a nice day!

Answer 7

This question has been asked hundreds of times and the answer is always the same. The probability of extraterrestrial aliens visiting the Earth is vanishingly small. End of story.

Answer 8

xc yes, of course. If you believe we would be the only intelligent species in the whole universe, then you'd be extremely arrogant.
Another point, of course, is the question whether we will ever know about them or they about us ... this probability is extremely small, at least as long as we live in the boundaries of speed of light ...

Answer 9

Yes. they exist

Answer 10

Who do you think would know? Nobody knows. Many people believe they have seen them or been abducted by them or seen UFO's and whether they have not is the issue. Someday I believe we will find them!

Answer 11

My answer is... maybe. We cant prove that they do, but then again, we can't prove that they dont. God gave us an incredible world. I wouldnt be surprised if He made something else too
