That is the naïve perspective. Nothing(ness) is homogenous, isotopic and uniform. What we have observed from those kind of systems is that they are unstable and tend to develop imbalances and irregularities. Perfection is death, the only way you can go from there is imperfection/decay.
Which is to say that Nothing became Something because it had to. It is the natural order. Any putative causa prima is superfluous.
