The source of witches? In which period and why?

Ancient witches are descendants of ancient shamans, who believe in the Nordic Goddess of the Earth and the Goddess of the Earth in Greek mythology. And know a lot about divination methods and the configuration of potions. Accurately speaking, witches should be witches and kind. (The witches mentioned here are not witches of Japanese Shintoism. Wizards generally use potions in a mild way, similar to the consumption of traditional Chinese medicine, such as putting them in soup. There is no such thing as boiling frogs. What Christianity said in15th century and16th century is that those who sign contracts with demons are not real witches, but devil worshippers. Witches are heretics rather than heresies. They serve the poor, don't curse people, and because witches don't use magic that can make big profits, they are not favored by nobles. While alchemists and magicians are active among businessmen such as capitalists and nobles. Modern Witches Modern witches have their own beliefs and become "Wiccans". The "Wicca" here is what people generally call modern witchcraft. They hold eight ceremonies a year, which will change and vary according to different regions and climates. Nowadays, many people don't understand the origin of the word "Wicca" and think that this word has nothing to do with witches. In fact, Wicca also refers to modern witches. Witches' magic is mostly potions and divination. Nowadays, many people say that they believe in witchcraft, but they summon many strange souls and so on. In fact, it is not the traditional magic of modern witches, nor does summoning magic belong to witchcraft, let alone summoning evil spirits such as demons.
