- Living things came into existence.
- Living things cannot come from nonliving things.
- Therefore a supernatural being created living things.
- Abiogenesis, the theory that life evolved from nonliving matter, is plausible.
- If a theory is plausible, no competing theory is reasonable to believe.
- Therefore, it’s not reasonable to believe that a supernatural being created living things
Sketch of Origin of life
- Simple organic molecules were formed, e.g. sugars, nucleic acids, amino acids.
- Replicating molecules evolved and began to undergo natural selection.
- Replicating molecules became enclosed within a cell membrane.
- Some cells began to evolve modern metabolic processes and out-competed those with older forms of metabolism.
- Multicellular organisms evolved.
- In the 1953 Miller-Urey experiment amino acids were produced from a mixture of water vapor, methane, ammonia, and molecular hydrogen, zapped by electricity.
