Pagans occultists theosophists etc - why did all peoples used to think that they are siblings of the Gods?

I have to agree with Nekhtet- most of your post is too tered to really make heads or tails of it. Yes, many religions felt as tho they were connected to the gods, and some religions did have a form of demigod (such as the pharoah being the living form of Heru). However, from what I've read, there wasn't really an "elite" few that were the sons of gods, perhaps what you're reading is meant ot be read figuratively, and not literally.
