How can it not be when we can see the same entity, the human being, develop from zygote to adult.But not a human being.
Don't keep making baseless claims
What on earth are you imagining? a hair follicle is an organ found in the skin of the human being. How can a organ of the human being, be the human being. Have you got many hair follicles as friends?We could replace "fertilized egg" with "hair follicle" in your above paragraph, and it would make just as much sense.
