Understanding the etymology of the word primordial is helpful in understanding what it means in this particular context. The term "primordial soup" has been used by scientists to describe the idea that life began from a series of chemical reactions in a warm pond on Earth's surface. As seen from the question, the word dates back to the late 14th century. It came from the Latin word primordialis, meaning "first of all" or "original." Looking back at the context of the word, it would make sense that "primordial soup" is considered the beginning of all life, because the word means "original."
T<span>he history of "primordial" began when the Latin words primus (meaning "first") and "ordiri" (meaning "to begin") came together to form "primordium," the Latin word for "origin." When it entered English in the 14th century, "primordial" was used in the general sense "primeval." so i makes better sense in the passage</span>
