ELI5 Why does the discovery of Kepler-452b is such a big news even though it is so far that we won`t ever reach it ?

What's exciting to me is that this planet is Earth-like, orbiting a sun-like star, and has been in its habitable zone for a few billion years *more* than we've been orbiting our sun. This means there is a very high chance that life has existed or does exist on this planet. A higher chance than any other planet we have discovered AFAIK. That's huge to me. It's exciting. We now know more about our universe. We know that planets that can potentially sustain life aren't quite as rare as we thought. What *isn't* interesting about that?? It's really fucking cool. Yeah, we can't go there quite yet but that isn't the point. Discoveries fuel the flames of discoverers. Galileo was discovering shit in the sky left and right 300 years before humans figured out how to fly. Maybe in 300 years we will have the ability to get to Kepler-452b. But of course that wouldn't happen if no one knew it was there to begin with.
