There's 8 bilion ppl in the world. Of that number, it's extremely likely a few know. I am not among them, but it's good to remain open-minded. Important to separate what is known (by the informed public) from speculation and information from those who may know. When someone says they know, I have no way of knowing if they know or if they're speculating which is fine. Much of it may be speculation - it's not possible to say. Everyone is free to speculate.
