By pure statistical likelihood it is more likely than not that there is extra terrestrial life in the universe, be it intelligent or not.
It is equally likely that there is extra dimensional life (if quantum physics is to be believed)
But as yet there is no actual evidence, or none that is widely known, it is therefore best to assume that it is irrelevant to us at this time.
However on purely circumstantial evidence alien life is more likely than god(s)

I believe there is a scientific basis for all paranormal experience....we just haven't approached it how the paranormal "works".

I believe the limitation of light speed on interstellar travel makes visitation by extraterrestrial life extremely unlikely. On the other hand, I believe the universe is filled with intelligent life.

NO! We are the only ones! We are special in the universe. I was told so,,,,,,by a ,,,,,,,,,invisible man in the sky........so there.

Life yes. Life as we know it, maybe. Intelligent life, unlikely. Little green men, no.

When we're shown photos of outer space , and all the billions of stars , knowing that those stars have even more planets , that even our strongest microscopes don't see , to me , it's reasonable , considering the huge variety and immense numbers of life forms on our planet alone , that there are other life forms out there . At this point though , the chances of us ever coming into contact with any of them are extremely unlikely .

"possibility"? How could there not be the possibility? Do we know?...I don't myself but since our universe is, to me, incomprehensibly large I think it's likely. Also, your question simply says extraterrestrial "life", not really specifying whether one thinks there is life that is as complex or....mmmm...advanced as humans. I wonder if less evolved lifeforms are even more likely.

Is it possible? Of course. Because we are.....
One cannot say for sure about much. I truly think that if there are they would have basically the same problems of huge amounts of time and extreme radiation as we would. Most life in the universe is probably microbial.

Anything is possible, and with such a vast universe still constantly expanding and innumerable galaxies, planets, stars, etcetera, the statistical probabilities, even plausible.

Probably yes, but universe is so huge and old that they can be too far or/and in a different stage of biological evolution or civilization level that makes contact impossible.

I think it's inevitable that life has developed somewhere else within the universe. While we don't know exactly how life came about on Earth, we know some of the requisites of abiogenesis and the overwhelming size of the universe and staggering number of galaxies makes it hard to imagine that life in some form didn't develop elsewhere.

Considering the apparent size and age of the universe, I assume life has developed elsewhere.

Why not?

But more to the point, why would they have anything to do with a rabid species like us.

Do you walk down a dimly lit alleyway in the most violent part of town after dark?

Common sense says no!

So because we have no contact may mean they are very sensible.

Recognising the possibility is the only sensible position, since it's a huge universe and we know there are vast numbers of planets now. But we need evidence.

On UFOs, some disparage all sightings and accounts and video and photos. What I ask is: ok, will someone with expertise or authority please explain what all the pictures and videos are. What are they, what natural or terrestrial phenomena explains them. I am very interested in knowing. But there is nothing. They've stopped with the usual suspects -- ball lightning, Jupiter, clouds, meteors and alike. Sometimes they wheel out government scientist spokes-spinner dancing bears like Neil Degrasse Tyson to do his laugh a minute routine, "there ain't nothing to see hear, folks," but not very convincingly. Since I have no confidence in the word of Power, in any of its forms, anymore, I take nothing from them at face value, including this subject.

It's possible, but if they can't make bikes fly or bleed acid, what's the point?

The universe is a big place, but time is also a big duration. So I think it's likely some other place in this universe may be right for the emergence of life, but it's such a rare occurrence that it may be very unlikely that life might emerge in one location that's anywhere near another before the other has already run it's course and perished.
