Since there is no evidence of intelligent life beyond Earth an accurate answer does not exist. However seeing as intelligent life is possible, I can narrow the likelyhood of intelligent life in our galaxy to be between 0 and 100%.
Isaac Asimov wrote that, in a decent-sized galaxy such as ours, odds indicate there would be a million planets with intelligent life equal or greater than Earth's.
Is there life in other galaxies? We currently have no way of knowing, although it seems quite likely. A galaxy is a big place.
Very likely, their are thousands maybe even millions of planets in the galaxy that are habitable, than their are trillions of galaxies.
The only one that humans are currently aware of is Earth. No other planet in our own solar system has intelligent life, and there is no conclusive evidence as of yet that intelligent life exists elsewhere.
since there are billions of Galaxy's and planets we don't know about, i would be surprised if there wasn't intelligent life on at least some of them.
No.
Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.
No one knows
None, buddy, we are all alone. But if you want to keep on dreaming, go ahead. Perhaps I am wrong. By the way, stars are too hot to harbour any kind of life. Perhaps some planets even in our galaxy have intelligent life. I, personally, doubt it.
Yes, other planets do exist in our galaxy and beyond. There are thousands of confirmed exoplanets that have been discovered orbiting other stars in the Milky Way galaxy. Some of these planets may have conditions that could potentially support life.
Many scientists consider the possibility life exists elsewhere in our universe (and more particularly even within our own galaxy) quite likely. A few do not think it is likely.
It is not currently known whether there are other planets with intelligent life... or with any type of life for that matter. It does seem likely, considering the huge amount of stars in the Universe, most of which seem to have planets.
