You can't skip the fertilization part and jump straight to brain activity as the beginning of a life. Even once you are brain dead, cells are still growing.
Layman doesn't understand "cycle."
A cycle such as a life cycle or biochemical pathway is circular. Where does a circle begin or end? In the case of a cycle, we pick an arbitrary point which then becomes the starting point by convention when enough sources agree upon using the same arbitrary starting point as the starting point.
In your example, human life begins at fertilization. However, oogenesis needs to occur before fertilization.
Long story short, which came first in the life cycle of the chicken; the chicken or the egg?
