The human body was once a huge mystery to scientists In the 18th century, they had a highly entertaining proposal about the origin of new cells in the body. It was believed new cells in the body were "spontaneously generated from available matter". You could say the scientists of the time believed in magic🤔 Luckily for us and regrettably for magic, the process of new cells is now well researched. Everything happens by mitosis — cell division, with the formation of two identical daughter cells☝🏻
