First of all this was something I'm still reading about, because it did open a doorway for me and may open similar to anyone else. Second of all, what I am about to tell you is not meant to question one's beliefs, but if it happens I apologize. If anything it provides insight to where certain beliefs come from. So without further adieu:
For context, while I do talk about religion, Astrology and boast my Wiccan and Native beliefs until I am blue in the mouth, there is something I must convey to you. Whether I believe in it or not, I am not always right. Even if I believe in some things, there will always be things that will contradict them, but I often at best try to find a compromise. However what I read so far, this specific book, while not made me question my own beliefs, but it did offer a 3D insight to where my beliefs come from. Ladies and gentleman I present to you, Chariots of the Gods? A book published in 1968, written by Erich Von Daniken. Whom theorized that a lot of things in relation to all the world's religions equated to, or was directly influenced by Extraterrestrial life. Now despite my own combo beliefs of Wiccan, Native and Some Christianity, the things I read in this book, made too much sense for me one way or the other. Now what I am talking about is not meant to offend or at the very least make people question their faiths, but to summarize it, this person believes that all the Gods our respective cultures witnessed over the millions of years we been on this planet, may have been an alien influence one way or another. In my case I was always in the divide between Science and Magic. I understood the magic aspect to some extent, but the science was way more complex and complicated until now. In theory, if all the Gods and Goddesses and other beings like Angels are of alien influence, chances are a huge fraction of human population could be part alien, based on what you believe what happened way back when.
Now this is something I don't expect you to believe right off the bat, but I do recommend you read it, even if you don't believe a word of it. It blew my mind. It may do the same for yours.
Until then, take care, stay safe and stay tuned for more.
