Our need for certainty and predictable outcomes..
That is a requirement of science and the scientific method.
..is a biological imperative and evolved as a method of survival.
That is a circular argument.
I could rephrase it slightly.
Our need for certainty and predictable outcomes is a biological imperative imbued in us by our creator as a method of survival. But wanting certainty does not mean all is and can be certain just because it makes us more comfortable.
