An outdated scientific hypothesis known as the spontaneous generation theory proposed that living things may develop spontaneously from inanimate objects and that this process frequently occurs in nature. It also described how life first emerged from inanimate objects. According to the hypothesis, dead meat may produce maggots, or a slice of cheese and bread wrapped and placed in a corner could produce mice in a matter of weeks.

The concept of spontaneous theory was first put forth by the Greek philosopher Aristotle (384–322 BC), who is considered one of the earliest scholars to have done so. According to Aristotle, if nonliving material contained pneuma (also known as “vital heat”), life may have developed from it.

Aristotle postulated that plants and animals could emerge from earth and liquid since there is “vital heat” or “soul” within the air, water, and earth.

An example of the hypothetical spontaneous generation theory is the old-fashioned belief that worms might be produced from dirt and water.
