What were the different theories about the origins of the Black Death?

There were several theories about the origins of the Black Death. One theory suggested that the disease originated in China or Central Asia and spread along trade routes, such as the Silk Road. Another theory proposed that the disease was brought to Europe by Mongol armies during their conquests. Some believed that the disease was a punishment from God, while others blamed Jews, lepers, or other marginalized groups for spreading the disease.
