The majority opinion I believe is that there is no common ancestor to all of today's languages, implying there have been several languages without parents. Of course, that's a thin majority, and those that believe it aren't that attached because there's no real way to know for sure. It would be neat if languages all had a common ancestor though, because that would leave open the possibility that language developed evolutionarily alongside our ability to understand it. Then maybe no language ever would have been spontaneous.
