How life formed? In the beginning of life on Earth , amino acid form via natural chemical reaction to life and it is regard as “ the building blocks of life” In the theory of abiogenisis, “ Replication” and “ Metabolism” are two processes to go through in life. Billion years after formation of Earth itself, there are several hypothesis about early life. The iron sulfur world theory and RNA world hypothesis are key element.
