Stringing words together that "this could have happened", there is a possibility that", etc. on this site does not in any way, shape or form constitute an "explanation".
I have an equivalent "explanation" for gravity. It is "possible" that angels and cherubim are floating around and keep pushing us back so we do not float away from earth. And that maybe pixies "could be" holding up airplanes in flight, so there is no need of any of this "naturalistic empiricism" to pollute children's minds.
