I highly doubt we will find an independent emergence of life in the same solar system (if a meteor/comet transferred biomaterial from one body to another, that would not be "independent").

If we do, however, that would be an observation (albeit a singular one) suggesting that the universe might absolutely be teeming with life (though not necessarily one that can communicate).

Or, the "precursors" seeded the universe with life according to some specific plan, and that plan called for multiple "experiments" in this particular system.
