Atheism, as an explicit position, can be either the affirmation of the nonexistence of gods, or the rejection of theism. It is also defined more broadly as synonymous with any form of nontheism, including the simple absence of belief in deities.
Now, once I was brainstorming with myself about dark magic and whether dark magic's existence should be an indicator that god exists. I thought so because dark magic in many major religions is performed through entities that are defined and described in holy books, for instance jinn (genie) in Koran. That was back in a time where I was unaware of the quantum phenomena and my religious culture was not as rich as it is now.
Recently, I don't think that the existence of dark magic entails the existance of god (or any other unique, lonely creator whatsoever). Here, I am not putting any argument towards the existence of god. Neither pro nor contra. This is not the question I am trying to answer at that moment in this post.
I am talking about something else, I am emphasizing a distinction, an analytic approach. There may be demons, fairies, genie regardless of the existence of an organized religion and any god that can be associated to it.
I am telling all these because of the fact that many people tend to hold many irrelevant bits and pieces of occult information together.
I see somebody talking about the law of attraction and then move to some other paranormal topic like UFOs, life after death, telepathy or telekinesis etc. just after two paragraphs. This sounds non-sense. People approach to those topics like as if they are being sold together in a market. You have to buy all of them, you can't just be interested in life after death, you also have to be interested in UFOs.
So, this is a huge non-sense. And when an atheist does reject some paranormal phenomena just because he rejects the existence of god, then this is a logical fallacy. This is not a pack of thought that you have to choose. We don't have to choose what we will believe in among packages of predetermined, prepared thought.
Thus, you can be an atheist and a mystic person at the same time. This is crystal clear to me, two irrelevant notions are really irrelevant.
Just to provide an analytic approach to how we think.
