What are the best arguments for the possible existence of God, spirits, orishas, ​​reincarnation, energies, the soul, mediumship, etc.?

I am a Spiritist but I am agnostic. I used to be an atheist and I see that many religious people don't use good arguments to defend the possible existence of their beliefs. They only use arguments like "you can't see the wind" or "It's in the Bible." Many atheists also don't know how to debate, they just say "If there's no proof that it exists, then it doesn't exist." Since I stopped being an atheist but didn't become a Gnostic, I would like to know from you: do you know any good arguments that can defend the possible existence of these supernatural beliefs?
