My opinion on this article is, that there is maybe another planet like ours but it may not hold life. It's so hard to see if there is water or not ,or if there is oxygen or not. I mean, if we ever had to move, we should try and find one of these planets. Maybe, they can support life. If they can, we could possibly have a whole new planet to live on. How we would get there I'm not sure. But I'm sure we can find away. We got a man on the moon.
