I don't believe in supernatural things and also God

[Lillian]

I don't believe in supernatural things because I think everything can be explained by scientific experiment and observation. If it is true that supernatural things exist then the probability that God exists is more than 50%. Although I was born a Christian, my faith has been very shaky because I don't believe in supernatural things. If it is true that witchcraft exists then it is true that God exists. If it is true that supernatural powers exist then God exist but in my opinion, there is nothing like a supernatural being or thing because I have never experienced anything like that. In my opinion, witchcraft does not exist, Ghosts do not exist, etc. Do you think supernatural beings and supernatural powers exist?
