answer:I have my doubts, but I like the idea. Earth is the perfect distance from the sun, with a moon that stabilizes its rotation causing predictable seasons, more or less, and makes it inhabitable. I remember once reading that the moon is some sort of lucky event where a celestial body flying or floating by the earth was pulled into its gravitational pull, and the two, earth and the moon, were forever united in a special symbiosis of sorts. Not sure if the thinking is different on that now? I am not up on astronomy and the universe at all. So, anyway, this would mean statisically for a similar “earth” to be somewhere is unlikely. But, anything is possilbe. The universe is so vast.
