We know that life is possible, because we exist. Apply that possibility to near-infinity and the chances that it has only happened once are improbable to the point of impossibility.
And yet, as you say, zero evidence of other intelligent alien life... but that stops being a paradox if you take the bold part out of the equation. True that even at the fastest sub-light speeds you could cross the galaxy in a fraction of that time... but would it ever be feasible or desirable? Would any being intelligent enough to develop the technology to travel through space for generations, taking YEARS to even get from one star to the next, actually bother to do so? IMO the absence of "warp" or "wormhole" travel makes the exploration of anything but the "nearest" star systems impractical. It probably simply can't be done.

Yeah i agree that no more life in the universe is highly unlikely.Life on Earth only took a very short amount of time to occur after the planet became less volatile.Only a few hundred million years I believe.If it happened that quickly here then chances are it's happened everywhere.There will be planets still going through their cave man era,Roman empire type era and also much more advanced than us.
