The fuzzyness that I am comfortable is a matter of hours, less than 12. And it's due to ignorance.

The fuzzyness the law tolerates is a matter of up to 9 months, and due to wishful thinking in order to justify the intentional, elective killing of human beings by other human beings.

So you contend that a precise time of beginning exists but that we just don't know specifically when it is.

So, not being able to observe it, how can we know that such a nonarbitrary dividing time nevertheless must exist?
