The plague was not "created" by anyone. It is a disease caused by the bacterium Yersinia pestis.
While no individual or group intentionally created the plague, understanding its origins and spread helps clarify the question:
-
Natural Origin: The bacterium Yersinia pestis evolved naturally. It's believed to have originated in Asia over 2,000 years ago.
-
Spread by Natural Means: The plague is primarily spread by fleas that live on rodents. Human outbreaks usually occur when infected fleas bite humans after the rodents they typically feed on die. Trade routes, particularly maritime routes, are thought to have significantly contributed to the rapid spread of the plague across continents.
-
No Human Creator: There's no evidence to suggest that any person or group deliberately created or engineered the plague bacterium. Its emergence and spread are natural, though exacerbated by human activities such as trade and poor sanitation.
-
Early Existence in Europe: Recent research suggests that Yersinia pestis may have been present in Europe as early as 3000 B.C., predating previous estimates.
In summary, the plague is a naturally occurring disease caused by a bacterium and spread through natural means, not the result of any intentional creation.
