The very early stage of a process does not equal the final stage of a human being. The scaffolding and foundation for a house is not a functional, finished home you can live in...
Begging The Question
If the scaffolding of the house is not a house, at what point during the construction does it become a house? This is undefined, just as the point at which a "fetus" becomes a "baby" is undefined, and it is a fallacy to pretend that "it is not defined" means "it is not a problem." You are assuming that conclusion.
