I’ve been down desert roads in New Mexico, walking and hitchhiking also in Montana, Canada, and Oregon sometimes in civilization sometimes in the wilderness I suppose alien beings just don’t want me to see them. I’ve been there and done that.❤

The Vatican has built a landing pad for alien craft. Why are they not landing there? Why are they not taking time to truly communicate with us? Your video says they landed and took off why didn’t they stay there? Wait for someone to show up to talk to them Nanu Nanu❤

Admiral Byrd said he flew his plane into a large hole, plane was tractor beam, saw a shimmering crystal city, met the supreme being, they told him humans are going down a dark path with their nuclear weapons, released him & sent him back. I believe in Byrd's account, as he is a man like me, just speaking plainly as a matter of fact. If it happens, it happens.
