At the same time, it's pretty clear we need to get out there (ultimately much beyond the galaxy itself) if we are to solve certain questions. And there's a general idea that a purpose of life may be to "spread" through the universe — like, why die here on this planet instead of settling the universe... given the actual choice, there's no solution but to leave eventually, when your star dies (if only locally to "fix" it by adding more fuel in it, e.g. hydrogen). So this, if true, is really just one more reason on top of an already high pile as I see it.
