The term that describes the misconception that nonliving things can produce living things is abiogenesis. This concept refers to the idea that life can arise spontaneously from nonliving matter under certain conditions. Historically, prior to the acceptance of biogenesis—which states that all living things arise from existing living organisms—there was a belief that complex organisms could emerge from inanimate substances, such as the idea that mice could come from rags or grain.

Abiogenesis is significant in the study of the origins of life, and while modern science acknowledges that life must come from pre-existing life, understanding abiogenesis helps to frame discussions around how life on Earth may have initially emerged from nonliving components through chemical processes.

Biological evolution, on the other hand, explains how living organisms change over time through processes like natural selection and does not pertain to the origins of life itself. Photosynthesis is a process by which living organisms convert light energy into chemical energy and is related to how life sustains itself rather than its origin. Metabolism encompasses the chemical reactions that occur within a living organism to maintain life, focusing on the functions of already living organisms rather than the emergence of life from nonliving materials.
