why does every organism we've studied seem to descend from a single ancestor if it's so easy for life to arise from a barren soup?

That one was successful. A million others could easily have arisen before it but been unsuccessful. A million others could have arisen afterwards but failed to compete with that single ancestor. And it's nearly impossible for them to leave any evidence of their existence.
