Spontaneous generation believed that everything that had life was either arose from the elements of an egg ,seed or  other means of reproduction. Aristotle who based some of his fine works and studies on the ideas of Anaximander , Hippolytus , and Anaxagoras , all of them who believed that stressed the fact that life could spontaneously come from being inanimate matter like slime , mud , and earth when exposed to sun light. Aristotle had his own ideas  on the ways maggots would  seemingly generate out of dead animals carcass , or barnacles would form  on the hull of a boat . This theory that life could literally spring from nothing managed to persist for hundreds of years after Aristotle, and was even being proposed by some scientists as recently as the 1700s.
The adoption of the scientific method that many of the classical theories like spontaneous generation that started to be tested. once it was tested it failed. famed scientist Louis Pasteur showed that maggots would  not appear on a piece of mean that was not concealed in a zip loc bag. Using a microscope showed that that these insects were formed by airborne microorganisms not by spontaneous generation.
