Redi
In the 1600's, the Italian scientist Francisco Redi performed experiments that showed that flies did not spontaneously generate from raw meat.

Francesco Redi
Francesco Redi is credited with disproving spontaneous generation in the 17th century. Through his experiments with meat in jars, he demonstrated that maggots only appeared on meat when flies laid eggs on it, not from the meat itself spontaneously generating them.
The purpose was so the flies won't get in the jar.
Flies are attracted to meat and will lay eggs on the meat, where they quickly hatch into maggots. But the flies are not indigenous to the meat.
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
Scientists use the scientific method, which involves making observations, forming a hypothesis, conducting experiments to test the hypothesis, analyzing the data, and drawing conclusions. In the case of Redi's experiment with rotting meat, Redi observed that maggots appeared on meat left out in the open, so he hypothesized that flies were responsible. He designed an experiment to test his hypothesis by covering the meat with a mesh to prevent flies from landing on it, which led to the conclusion that flies were indeed the source of the maggots.

no it doesnt
Rotting meat doesn't create flies. Rotting meat attracts flies that lay their eggs on the meat. These eggs hatch and maggots emerge and proceed to feed off the rotten meat. After a period as a chrysalis, the maggots change and emerge as adult flies.
