Prebiotic Earth Conditions and Abiotic Synthesis
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Before life existed, early Earth's atmosphere and energy sources could, under one long-standing hypothesis, have driven abiotic synthesis of simple organic molecules from inorganic starting material.
Show
Volcanic gases plus lightning-like energy in an early-Earth model yield amino acids without any living cell present to make them.
Watch for
Forming organic molecules abiotically is not forming life — self-replication and heredity remain separate, unexplained steps.
