Note: you may believe that life started in multiple places at multiple times throughout the universe, but the thread is concerned only about the strain of life that populated the earth.
Not to get off on a tangent, but this is why the study of the deep oceans is important; it's not just an obstacle so NASA has a smaller budget, it helps answer questions like these. But that goes two ways. If NASA finds life somewhere that isn't based on the same organic atoms we use, then that indicates that life can arise in places other than water worlds, and that would completely change how we look at biology.

Would we even recognize other life forms if we saw them. I know, "Of course we would," you are probably thinking, but What if a lifeform had a lifespan of thousands of years and moved extremely slowly, or what if their bodies were extremely large? It would be fairly difficult to recognize these lifeforms from our tiny scope on life.
