Before Pasteur's experiments, the prevailing belief was in spontaneous generation, the idea that living organisms could arise from non-living matter. Many thought that cells and microorganisms could spontaneously emerge from decaying materials or nutrient-rich environments without any biological source. This misconception persisted despite the lack of empirical evidence, as people did not yet understand the role of microorganisms in fermentation and decay. Pasteur's work ultimately debunked this theory, demonstrating that microbial life comes from existing cells rather than arising spontaneously.
Before Pasteur's experiments, people generally believed in the theory of spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter. Pasteur's experiments helped disprove this theory and provided evidence for the concept of biogenesis, which states that living organisms can only arise from pre-existing living cells.

Many rather vague and poorly defined ideas about the origin of disease existed before the introduction of the germ theory. Disease was attributed to bad air (as in malaria, meaning bad air) or from an imbalance of "humours" meaning certain essential bodily fluids, of which you could have too much or too little. Many mystical attributions also existed; evils spirits, witches, malevolent deities, astrological influences, etc.
Known as the founder of microbiology, Pasteur discovered the role of bacteria in fermentation. His experiments with bacteria conclusively disproved the theory of spontaneous generation and led to the theory that infection is caused by germs. Extrapolating from this knowledge, Pasteur then developed a process in which liquids such as milk were heated to kill all bacteria and moulds already present within them. This process became known as pasteurisation. Recognising that infectious diseases are caused by microorganisms, Pasteur's research soon led others to investigate sterilisation, disinfection, vaccines, and eventually antibiotics. Pasteur created and tested vaccines for diphtheria, cholera, yellow fever, plague, rabies, anthrax, and tuberculosis. (source: today.wmit.net - 27 December)

Before Pasteur's experiments, many people believed in the concept of spontaneous generation, which suggested that living organisms could arise from non-living matter. For example, it was thought that maggots could spontaneously appear from decaying meat. This belief persisted despite the lack of scientific evidence, as the processes of microbial life were not well understood. Pasteur's experiments with beef broth and S-shaped tubing ultimately disproved spontaneous generation and established the importance of microorganisms in fermentation and disease.
Louis Pasteur was able to convince others of his germ theory by performing extensive experiments. Through these experiments, he was able to disprove spontaneous generation and prove biogenesis.

Louis Pasteur.
Cells came from nonliving things.or Cells could generate spontaneously.
He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.
The difficulties that Louis Pasteur had doing the research was that people did not know about him studing rabies so he tried to keep it a secret.

It is important to people today that Louis Pasteur discovered things because if he didnt many people would of died for rabies and other things he discovered......
