Why do Angels have wings?
In ancient times it was thought that only creatures with wings can fly. So when all-powerful Angels were seen in the sky and on the mountain tops, the people who saw them concluded that if they got there, they must have used their wings to fly.
So if an animal, a special person or a cloud in the sky seems Angelic to you, don't doubt your vision.
You have the experience to know that airplanes and spaceships can fly.
And you know that your Angels can do so much more. So trust what you see and never stop talking to them.
