Well the closest exoplanet is proxima centauri B. That's 4 light years away. Closest star is Alpha Centauri, that's 4.3 light years away. So if there's life around those at the very minimal it'd be Voyager that they ..find. Voyager is nearing 15 billion miles away. Subtract that from the relative distance 4 light years is, like 1.06(I think) trillion miles for one light year. Then do the math of 16000 mph to cover that distance, you'd have plus a return trip(if whatever was sent was at that same speed) and you've got a rough idea.
Translation, dependent on MANY ifs, A VERY long time.
