Primordial Soup Hypothesis: The Foundation Of Life

Water with amino acids is a primordial soup hypothesis, which proposes that life arose from a solution of organic molecules in water. This hypothesis is supported by the Miller-Urey experiment, which demonstrated that amino acids could be synthesized from inorganic compounds under conditions that may have existed on early Earth. Amino acids are the building blocks of proteins, which are essential for life. The presence of amino acids in water suggests that the conditions necessary for the origin of life may have existed on early Earth.
