alea, a better response is that no argument can be made for a singular event, rather that that which is extant derives from one event, of which there may well have been many, and sampling error (genetic drift) and selection (survival of the fittest) both push towards a likelihood of progeny of just one event being around today.

Your last point: if so, then why does it appear to have been a singular event on this planet. Aren't we all branches of the only tree of life on earth?

For me, this is the really perplexing question, so the more you know about this the better! I have never understood why there are no unrelated species. I assumed this was because the origin of life was a rare thing.
