Absolutely, the galaxy has the ingredients to make life wherever possible HOWEVER intelligent life is another matter.
It has taken 5 billion years for intelligent life on Earth and this is after many accidents including around 7 mass extinctions.
The recipe for making intelligent life has been very complex and is it possible it could happen again?
If humans died out what are the chances of another animal becoming intelligent? - probably none.
So let's say we know there is a high possibility of life on a planet 1000 light years away, how do we visit or they visit us?
At this point there is zero evidence of magic ways to do this, it's impossible.
Well this is where the Fermi Paradox comes in.
On Earth intelligent life that can communicate with other supposed Aliens has been around 10000 years or so, perhaps more perhaps less.
The chances of another planet 1000 light years away creating intelligent life with all the many accidents the planet would have to go through, would be virtually impossible at the same time as us.
Do you think humans will be here in 5 million years time? - I think not and they would come and go in a blink of the Galaxys Eye.
It's a lovely thought the Star Wars and Star Trek Galaxy but also very silly.
I agree with your assessment on the likelihood of intelligent life. But the fermi paradox is nothing but an interesting thought experiment and no more. We are able to listen to potential “alien” communications but that is not the same as communication. It should also be noted that at best we have been able to listen for “alien” signals for about 50 - 60 years.
The fermi paradox can’t he used as proof intelligence does not exist elsewhere, all it lends credibility to is that we haven’t the technology to hear/see them yet. We may never have.
Just for another thought experiment. Intelligent life could exist on the other side of our galaxy and we would never know. That goes for all the countless other galaxies we know exist.
