Saying that the idea of "a primordial soup produced the building blocks that eventually led to all life on earth" has failed because some extraordinarily limited experiments (spatially, chemically, temporally, and complexity limited) haven't produced cellular life is about like saying that the "fusion of hydrogen produces the heat of stars" theory has failed because we haven't been able to produce stable fusion here on earth. The scope of the effect that was likely produced in the primordial environment over billions of years is beyond basic human comprehension.
