Are science close to discovering the origin of life and the ability to create life from inanimate molecules?
In the natural sciences, abiogenesis, or origin of life, is the study of how life on Earth emerged from inanimate organic and inorganic molecules. Scientific research theorizes that abiogenesis occurred sometime between 4.4 and 3.5 billion years ago. By 2.4 billion years ago the ratio of stable isotopes of carbon (12C and 13C), iron (56Fe, 57Fe, and 58Fe) and sulfur (32S, 33S, 34S, and 36S) points to a biogenic origin of minerals and sediments and molecular biomarkers indicate photosynthesis.
