The universe is expanding faster and faster, so if some galaxy is believed to contain a life friendly planet we will never know whether there is life there since it is just getting more and more distant from us as time passes. It is a pointless search.

There's plenty time left before expansion is faster than the speed of light. First Andromeda will pass through our galaxy in about 3.75 billion years. Will we still be around to see it...

If we survive we'll eventually colonize the entire universe anyway. It's just a matter of time.

Not really, earth is set to be unable to support life between 1 and 2 billion years from now when the sun starts it's death phase by slowly becoming hotter and bigger, and eventually it explodes into a supernova in 3.5-4 billion years according to scientific estimates.

Water will no longer be able to exist in liqud state 1 billion years from now therefore earth won't be able to support life, it will be a lot hotter.
