Yes, I'm cautious with claiming proof or certainty, without mountains of incontrovertible evidence to back it up. It comes from a lifetime of knowing things, without being able to explain how I know them, and then not being believed.

But it is settled many times over in my own mind. Everybody's got their own evidence threshold, so I try to put the bits and pieces out there as neutrally as possible, trusting that people can draw their own conclusions.

Plus, sometimes I read it wrong ;)
