Curious why there is much less interest in the Pleiades, which is made of all of our same material and is very likely a "fork" of earth formed after the original mass that later became earth and moon colliding with another body in early history.

- HarHarVeryFunny 2y agoPerhaps, but given how sterile the moon appears to be, it's not obvious why the Pleidas would be any different, even assuming they were created by the same potentially life-seeding impact. I can see the purely historical interest in knowing how the earth and moon were formed, where our water came from, where terrestial life originated, etc, but it seems (maybe I'm wrong?) that a large part of the interest in extra-terrestial origin of life consideration is from people who don't want to believe that life is all-but-inevitable in the right conditions and therefore presumably did originate here (and very quickly after earth formed - within a few 100M years). However, if creation of life is an extremely rare event, then the likelihood of it having spread from such a rare source to any other compatible planet seems vanishingly small!
