No need to go nearly so far. Right here on Earth we have some quite
intelligent creatures with whom we have a difficult time
communicating, and we've evolved right next to them.
Dolphins and other cetaceans are clearly intelligent creatures.
They can conceptualize and communicate. The big difference between
us and them is not our brains, it's our hands. Our definitions of
"intelligent" have a lot to do with what can be put together or
manipulated by hands and fingers. Dolphins are intelligent
creatures, but they are never going to build radio broadcasting
equipment that will reach out to the stars. Doing any electronics
when you're obligated to always be surrounded by salt water is
quite a hurdle to leap.
Likewise, Chimpanzees, with whom we share most of our DNA and which
have some capacity to communicate and are quite bright, do not have
hands that are shaped well enough to build complex things like
radio transmitters. Given enough time Chimpanzees have the
potential to evolve into something that could build such devices.
So there may well be lots of intelligent beings all over the
universe, but we are unlikely to ever have anything to do with
them. We can't even define human intelligence very well.

I agree. I strongly suspect, however, that microbial life is going
to prove ubiquitous. And from there we'll get larger living things
on some planets, but exact, or close enough, analogues of Homo
sapiens sapiens could be such an unlikely occurrence that we might
well be the only examples in this universe.
And even if we're not the only ones in this universe, the odds of
others so much like us being in THIS galaxy are slim. The odds are
that they'd be in a galaxy billions of light years away, if they
exist. I do not think that we are ever going to communicate with
any creatures from other galaxies. Too bad that we can't even get
along with each other.
