I'm still having a hard time with this. You say you don't know, and from that you conclude that nobody else does either?

Surely somebody has spent time "researching the data, looking at the implications, and listening to the arguments"? Why are you so sure they should "admit" that they don't really know? Especially when so many have come out and said that they do?
