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%.
So far, mankind has not discovered any life on other planets, let alone intelligent life. There's barely any intelligent life on this planet!!!
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.
It is likely to discover new animals and species because we are not alone in this whole wide galaxy.
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.
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.
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.
There is no way of knowing that. Although the Drake Equation attempts an estimate, it is based almost entirely on speculation.
