Yes, they said "just" 40 light years away. Light travels 6 trillion miles in a single day. You do the math, but this discovery is completely meaningless as far as any of us or our families, generations removed.
Sadly, that fact will not stifle the dreamer talk coming from our "scientists." Just know this: there is absolutely no evidence of any kind that other civilizations exist "out there," or that, in some way, will will benefit from the NASA discovery.
