I do not know much about earth angles but I've contacted angels through ouija boards they have told my future how my friend can avoid drowning , I'll supposivly be a billionaire and make it from programming . It told me I would die in a fire. That's just part of my experience it told me much more if you want me to make a thread on it just ask me.
I don't know many things about earth angels and angels in general.However, I will gladly share my opinion of what I think they are!
My opinion on earth angels would be they are the workers of earth. By that I mean they make the trees, flowers, and anything nature related and when they fly the wind blows. They also give mother earth messages from anyone (or anything ) . This is just my opinion.
