I see the discussion continues apace since I last posted on this thread! All I would add is that Dr. Grier makes one important point. If the ETs are advanced enough to visit us from far away, they are clearly more technologically advanced than us. Yet to have reached this advanced state without having destroyed themselves suggests that they are also much more spiritually advanced. He suggests that they are non-aggressive, and that it is we who are aggressive and at risk of blowing ourselves up. I find that argument quite convincing. Mankind needs spirituality!

BTW, he says that his group makes contact via telepathy following meditation and going into trance states, and that some ETs have fine bodies (like astral bodies) - so quite a bit like this forum!
