I can't answer any of your questions. Sorry.
The answer to the first four has to do with a subject that is very popular in your time, publishing it in this post would put us at risk because there would be a 60 year time gap that is critical to maintaining the story. Also if I told you, we would be at risk as individuals, you and I, in that order.
I can't offer you proof either, in my time mental connections are key and we are the same. If you concentrate enough on my words you will be able to see that I am definitely not lying to you.
