Are two people really spending time arguing about if angels have belly buttons!!!??!!
Too funny!
A robust discussion of which came first; the chicken or the egg would be in order for the next topic.
The first chicken (Gallus gallus domesticus) resulted from a fertilized egg with one more genetic mutations that probably didn't make it all that different from his or her parents but still made it a preferable to a human in China 8000 years ago that he or she selected it for breeding.
Thus, it is incontrovertible that the egg came first.
