Even when I read it I could not find where Michael Horn states he knowingly gave false information, but i tend to miss things here and there
. Unfortunately its a tough call for folkes who need hard proof in science to get whats going on. There is so much deception being done in the scientific world and its part of the mind control agenda used on the populace. I personally take a balance of both science and my own syncromystical experience. I think Billy is genuine!
Good luck
