Jet again forced to believe

[Der/die AtheistIn]

My dad just randomly called me to talk to me, he does that quite often. He talked about some things including religion and spirituality. He said that at the time he was 30 someone showed him a trick to communicate with the spirit of his dead mom. A Bible was hanged and he asked some questions. The Bible rotated at right for yes and at left for no. After some questions he asked if it was right that he used this trick and the answer was no. Then WTF did his mom answer his questions in the first place?
Dad also said that I shouldn't do this thing, because nterfering with the spirit world could brake the balance between worlds. Then WTF would Gold allow us to communicate with it? Why wouldn't He stop any connection to the spirit world?
He told me that this experience made him feel uncomfortable and doesn't know why. I thought that maybe his subconscious knew that all of this was bullshit and was desperate because the conscious mind wouldn't listen.
He claimed that he knows maths and physics so he thinks logical, also he's not insane, so I shouldn't laugh (by the way, I didn't laugh, I only bit my lip).
Father stated that the Universe is complex and ballanced, and it must have been created by a God because of that. Then what created God?
After that he showed me the news. It was something about clinical death and out of body experience. An old physist said his theory about the other world and talked about out of body experience cases. Also a guy who claimed to have been very sick and healed after he saw a blond angel with blue eyes.
It's the fucking news! They lie all the time to get ratings! And that physist, how can we know that he was legit? Maybe he didn't deserve his degree, maybe he did deserve it but was lying, or maybe he's crazy or senile. And how can we know that the other guy wasn't lying or hallucinating?
Father doesn't believe in Hell, not in Eternal Hell at the very least, and he does aknowledge that some things in the Bible are false and written by men, like the Earth being flat.
He doesn't take criticism well at any topic including religion. I thought that maybe I should never tell him about my atheism, but then I asked myself what would he say if I would marry and not have a religious ceremony, or if I would have a child and not baptize it as an infant? I know that at that time I will not depend on him much, but i still don't want to fight with him.
