I was on my back porch, looking up at the stars, and I saw a very bright ball move across the sky very slowly, and it died out, like a light bulb. It didn't take off, there was no fast movement, it just wasn't there anymore. They do have a cloaking device, invisible capability. That to me is no longer a theory, it's reality. They can be invisible, they make no sound, they could be anywhere, anytime. Sorry, no photo. It happened so fast.
