7 janv. 1870 - Germ Theory

Description:

Theory states that Bacteria cause disease. Its about damn time, if you really think about it. But if this is here, no one before this event has any idea of the association between little creatures called bacteria and disease. So people are completely clueless before this ok. Lol in my notes, i wrote "Ew how tf they come up with vaccines before this??" Lol history humour.
