means The theorized mixture of water and simple organic chemicals on early Earth from which the first living cells are thought to have emerged.

from The phrase is usually traced to the 1920s, when scientists like Alexander Oparin and J.B.S. Haldane proposed that lightning, ultraviolet light, and volcanic heat could have driven simple molecules in Earth's ancient oceans and atmosphere to combine into the building blocks of life — an idea nicknamed 'primordial soup' or the 'prebiotic soup.' It gained lab credibility in 1952 with the Miller–Urey experiment, which zapped a flask of water and gases with electricity to simulate lightning, and really did produce amino acids. The exact 'recipe' of early Earth's chemistry is still debated, but the soup metaphor stuck because it captured something true: life's ingredients, simmering and colliding, long before anything was alive to taste it.
