Which of the following is not a scientific hypothesis for how life began?

Panspermia suggests that life exists throughout the Universe and is distributed by space dust, meteoroids, asteroids, comets, planetoids, or potentially by spacecraft in the form of unintended contamination by microorganisms. This is a testable hypothesis.

Abiogenesis is the natural process of life arising from non-living matter, such as simple organic compounds. This is a scientific hypothesis as it can be tested and explored through experiments.

The RNA World Hypothesis proposes that self-replicating ribonucleic acid (RNA) molecules were precursors to current life (which is based on deoxyribonucleic acid, or DNA). This is a scientific hypothesis because it can be tested through biochemical experiments.
