I think the credited view of evolution is that there was no design involved. It may indeed be true that the haphazard adaptations of breast milk to infant needs (and maternal limitations of resources) under selection pressure makes breast milk better food for babies than any human-designed infant formula, but that's an empirical question. It is possible in principle, at least, that human design could eventually make better (by whatever criterion you use to define "better") for human infants than breast milk.
