I think we all know about the Abrahamic religions: Christianity, Islam, and Judaism. Pretty old faith, yet still living and breathing. The story of one God, and creating everything including two humans who populated Earth with people of different races and skin colours (and don't make me speak about Noah).
Very old question in the occult circles, where do deities come from? We already do know about our power to create egregores, but could all the deities be like that? The creation of the mankind? I have spent quite some time summoning various spirits to the point of it becoming boring, the initial sense of dread quickly disappears and communication becomes casual over time, and maybe with just one exception, Death.
I think most occultists know about this, but I there are 7 planets representing 7 forces in the universe that affect our lives. Did you just notice how silly this looks? OK, it is scientifically proven that people are different when born during different seasons, but that's the thing of our environment, not about which one signs are planets in.
We are already old enough as a species to let the old faery tales go. After all, isn't it funnier to evoke a predator than some ancient blood cult creation. It's going to work either way. Anyway, whatever you do, and don't let your beliefs to limit your progress and do your best to understand modern science, medicine and technology.
