We do know enough about seven other planets to know that most of them probably don’t have or have ever had conditions suitable for life as we know it. (Mars may be the exception.) But that’s seven out of probably millions of planets in our galaxy. And there are billions of galaxies. We do know a little bit about a few hundred planets outside our galaxy. The easiest extrasolar planets to discover are the big gas giants, but we do know of others which maybe have conditions suitable for life. We just have no idea what conditions are like on them because they’re too far away. And then, what about the trillions of other planets we haven’t even discovered yet?
To simply imply that Earth is unique – instead of asking why it’s unique among the planets we know about – suggests that you know more about trillions of planets than I do. I look forward to your sharing that information with astronomers.
It has a powerful magnetic field that it is the thing that makes Aurora Borealis.
