Francesco Redi and Louis Pasteur, as well as Lazzaro Spallanzani and John Tyndall, all did scientific experiments (as opposed to philosophical writings) challenging the idea that life could quickly arise in the absence of any life from which other life could grow. This idea, formally dating back to the ancient Greeks, is called "spontaneous generation." The experiments of these four showed that spontaneous generation did not occur in situations that others thought it did. Like any good science controversy, other scientists did experiments that supported spontaneous generation, but Pasteur and Tyndall were able to do experiments that were rigorous enough to unambiguously disprove this idea.
Both Louis Pasteur and Francesco Redi conducted experiments to challenge the idea of spontaneous generation. Redi's experiment used decaying meat in covered and uncovered jars to demonstrate that maggots came from flies, not spontaneously from the meat. Pasteur's work with broth in swan-neck flasks showed that microorganisms were introduced from the air, rather than arising spontaneously, when the broth was left exposed. Both experiments provided crucial evidence supporting the theory of biogenesis, the idea that life arises from existing life.
Louis Pasteur was trying to reject the theory of spontaneous generation, which suggested that living organisms could arise from non-living matter. He conducted experiments to demonstrate that microorganisms come from pre-existing life, leading to the development of the germ theory of disease.
Louis Pasteur believed that milk contained harmful bacteria that caused spoilage and disease when left unpasteurized. He conducted experiments to demonstrate that heating milk to a certain temperature could kill these harmful organisms and make the milk safe for consumption.
The flask that was not exposed to air/germs and remained sealed represents the control in Louis Pasteur's experiment. This flask helped to demonstrate that it was the air/germs that caused the spoilage and not just the broth itself.
Francesco Redi is known for his experiments disproving spontaneous generation. Lazzaro Spallanzani proved that microorganisms cannot generate spontaneously in a closed environment. Louis Pasteur developed the germ theory of disease and pioneered pasteurization to prevent microbial contamination in food and beverages.
Francesco Redi, in 1668, showed that abiogenesis of maggots did not occur, and further experiments by Lazzaro Spallanzani (1768) and Louis Pasteur (1861) showed that many of the lifeforms thought "created" were those already invisibly present in the air or in other materials.
Redi and Pasteur helped to disprove spontaneous generation.
Bacteria
The experiments conducted by the scientist Louis Pasteur demonstrated the principle of biogenesis.
Louis Pasteur and Francesco Redi are two scientists who performed experiments that supported the idea that life can only arise from preexisting life. Pasteur's experiments with sterilized broth and Redi's experiments with sealed jars and decaying meat both demonstrated the principle of biogenesis.

Nothing in the bible disproved spontaneous generation, the scientists Louis Pasteur and Francesco Redi disproved spontaneous generation in a series of very careful experiments.
