While it’s a core belief of Abrahamic monotheist that there is no god but Gods practically speaking some people kept some traditionul/pagan belief. I think obviously about some Africans doing their own mix, but even in Europe, tons of Pagan belief stay around, stuff like knocking on woodor having a Christmas tree, let alone various form of witchcraft which are also illegal for Christians but quite common, no matter whether it’s an old man reading runes or a teen girl praying the moon because it looks cool on TikTok
