Truth is, not one scientist on the planet can answer this question. Oh, many will take a stab at it, but none actually know for sure. With scientists these days you hear alot of, "I think..." and "my opinion is..." Science used to be science, where unless it could be duplicated multiple times in some sort of experiment, test tube, or controlled environment, it wasn't even worth calling a hypothesis. Now, heck, as long as you think it sounds good, and you're sporting three letters after your name, it's a rock solid fact that you can write a book about. I long for the day when we go back to being investigators searching for facts, truth, and solid data. For those too young to know what I'm talking about, consider a favorite saying among doctors: "Today's textbooks are tomorrow's joke books." That saying didn't emerge from nothing, it came from generation after generation being taught hypothesis as if it were fact, and doctors trying to make a name for themselves rather than letting the data dictate their decisions.
