What is the special life force in the air called that people used to think created microbes?

spontaneous generation

Explanation:

Spontaneous generation is the myth that organisms could originate without the need to have descent from similar organisms (i.e., created spontaneously from the dust). This belief stated that organisms could arise from nonliving material. Louis Pasteur conducted experiments in order to show that this belief was false and thus confirm the theory of biogenesis, which states living organisms can be only generated by the reproduction of similar living organisms. Pasteur showed that microorganisms could not be developed in isolated sterilized tubes, but they could be developed in open tubes, thereby showing that reproduction (biogenesis) is the only source of living organisms.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
