I hear that.  If the Earth got destroyed but we had time to cram people
into livable spaceships?  Why send them across interstellar space to
where there *might* be a habitable planet, as opposed to building a
space station in the habitable orbit of the solar system they're already

Sure, there are challenges that would need to be solved to make a
livable space station.  They, and their risks, pale in comparison to what
comes with crossing several light years, when we've yet to send any
human being much beyond the dark side of the Moon - and then
there's the whole "gambling what's left of the human race on finding a
life-friendly planet" deal.  At least with something we build, we can
address the risks.
