So, if science is excited and feels it possible that we'll "discover" an Earth-like "twin" planet soon, why is it so implausible to consider that at least one such Earth-like "twin" might also be actively looking to "discover"
us ... or might have already done so, especially if they're a bit ahead of us technologically?

Once we've been "discovered", though, would they find us worthy of attention, or simply move on looking for more intelligent life, elsewhere?
