I saw exactly what he saw and thousands of others in Phoenix. I know he is saying he "thinks" it is otherworldly and I can't say I blame him for thinking that.
What I saw was approximately 2 miles wide. It was moving too slow to be suspended in the air like it was. There was absolutely no noise either.
"If" it is one of ours, where are they hiding it? How can you hide something that big?
There have even been sightings and reports (by credible witnesses) of it jumping to another location within a split second.
I honestly do not believe we are capable of that type of technology.
In addition to that, these black triangles have been reported for hundreds of years.
If I had never seen what I saw, I would find my own testimony a little bit "nutty". Sometimes, I wish I had never seen it.
